Error Page: Plug your Hammer compile log in and it will find most problems(and solutions!) immediately. Read the full errors page here: http://www.interlopers.net/errors/
Search : There's an extra big search box at the top of the forum, search your problem first in case it has been asked already.
Descriptive Topic Titles : Using "I have a problem" or "Another Error" is not really helpful.
Clear English : Text speak is not appreciated, keep it clear
Post Full Compile Logs: It helps if we can see the whole log, as the bit you picked out might not be the error.
As much information as possible : Try to be descriptive with any problems you are having, so people don't have to ask you again.
Images: If it helps post some images
Pass on your knowledge: If you've learnt something and someone else has a similar problem, try lending a hand.
