Here are a few pointers (stolen from the Ogre forum rules, only a selection I found most important)
Always search the forum and the Wiki before posting. You should also familiarise yourself with the API and Manual.
Summarise the topic accurately in the headline. For example "HELP!!" is not a valid headline, nor is "What is going on?". A good headline might read "alpha_reject behaving differently on GL rendersystem".
Do your homework first. Investigate your problem by experimenting with variations, looking at logs, and using your debugger. Problem solving is a learned skill, you have to DO it to become self sufficient. We're happy to help but expect some effort from you too.
Post just the pertinent details and explain what you've tried and what you've looked at already. Don't just post your entire codebase, say "it doesn't work!" and expect people to sort it out for you.
Be succinct. State the problem, the symptoms, the investigation in a structured and easy to read form. Blocks of rambling text will just get you ignored.
Post in proper English. If English isn't your first language, we'll cut you some slack, but there is no excuse for native English speakers to post contraction-filled, badly punctuated, grammatically random posts. This isn't a text message, people, and continually using contractions like 'U' and 'ur', and interspersing every second sentence with 'lol' will lead me to stop caring what you have to say in short order.
Don't 'bump' threads unless you have something more to add. If you didn't get a response the first time, it's likely that you didn't provide enough information, or people thought you hadn't done enough work of your own to justify a response. Or, they just might not have known the answer.
No political discussions, especially not in technical threads. If you really need to discuss those things, keep it inside Off-topic.
No spam or 'I like this' replies. While it might look obvious, this is necessary due to the excessive abuse of forums through spam-bots. We are often removing postings which are more or less clearly spam replies. Just don't let your posts look like a typical spam post such that it won't be deleted.[/quote]
