When posting a bug or feature request, be sure to give discriptive titles.Bad:
"Found a bug"
"I have an awesome idea!"
"Can you add this?"Good:
"Bug: Missing HUD Textures in Build 10"
"Request: MP3 Support"
Try to give at least SOME hint as to what the post is about.
Also, check if there are any threads already posted about the bug/suggestion you have and contribute to those rather than starting a new topic.
Update: If you have a feature request, please visit this thread for details on the feature vote system.
