    Welcome to the community . Let's boost our power throughout this year also. Important rules Join the community and collaborate as much as possible. Please remember to post in the correct topic. In this community, Information must be related only to subjects, exams, technical questions, theoretical questions, assignments and notices. Do not post protected university information, passwords or module keys. For such information contact lecturers, batch representatives or your social batch groups. New things are welcome. Almost anything related to SE Subjects. Never hesitate to ask questions here. Everyone here is to help everyone. Feedbacks are welcome. Do not forget to drop suggestions if any. Turn on notifications for this site. New changes will be notified. Don't share or publish any protected information to outside. ( Generally speaking, protect SE Department's information and SLIIT ) General Forum Rules 1. No Spam / Advertising / Self-promote in the forums These forums define spam as unsolicited advertisement for goods, services and/or other web sites, or posts with little, or completely unrelated content. Do not spam the forums with links to your site or product, or try to self-promote your website, business or forums etc. Spamming also includes sending private messages to a large number of different users. 2. Do not post copyright-infringing material Providing or asking for information on how to illegally obtain copyrighted materials is forbidden. 3. Do not post “offensive” posts, links or images Any material which constitutes defamation, harassment, or abuse is strictly prohibited. Material that is sexually or otherwise obscene, racist, or otherwise overly discriminatory is not permitted on these forums. This includes user pictures. Use common sense while posting. This is a web site for accountancy professionals. 4. Do not cross-post questions Please refrain from posting the same question in several forums. There is normally one forum which is most suitable in which to post your question. 5. Do not PM users asking for help Do not send private messages to any users asking for help. If you need help, make a new thread in the appropriate forum then the whole community can help and benefit. 6. Remain respectful of other members at all times All posts should be professional and courteous. You have every right to disagree with your fellow community members and explain your perspective. However, you are not free to attack, degrade, insult, or otherwise belittle them or the quality of this community. It does not matter what title or power you hold in these forums, you are expected to obey this rule. General Posting Guidelines We figured this was necessary because a lot of people come in and post threads without thinking, and without realizing that there is no possible way they could get help because of the way they posted the question. Here are some general guidelines. 1. Please use SEARCH first! There is a pretty good chance that unless you have some really odd or unique problem that it has been addressed on our forum before, please use the forum’s search feature first to see if there are already some good threads on the subject. 2. Be DESCRIPTIVE and Don’t use “stupid” topic names PLEASE post a descriptive topic name! Give a short summary of your problem IN THE SUBJECT. (Don’t use attention getting subjects, they don’t get attention and only annoy people). Here’s a great list of topic subjects YOU SHOULD NOT POST : Help me, Hello, Very urgent, I have a question Generally, ANYTHING similar to those is unacceptable. Just post your problem. Here is a good example of a way to post a question “how to calculate the sensitivity of net annual operating cash flows” or “where is the ACCA exam centre in Glasgow” Remember when people help you, they are doing YOU a favour Be patient, help people out by posting good descriptions of what you need help with, and not snapping at people with garbage such as “if you aren’t going to help don’t waste my time replying”. General Forum Questions Am I allowed more than one account? No, there is no reason why you should have more than one account at OpenTuition forums. If you are banned from the forums, please do not create a new account. If you continue to create new accounts after you have been banned, your IP address will be blocked from the forums. What happens if I break a rule? If you break a rule, then you will either be warned or banned. A ban of your user account may either be temporary or permanent. The administrators and moderators also have the right to edit, delete, move or close any thread or post as they see necessary, without prior warning. What happens if I see a thread/post which has broken a rule? Please report the thread/post to the moderators or admin. Wish you all the very Best in your studies and career !!! Thank You.
