i think thread tags are the best bet for organization. the release and WIP are a good start, if we could get people to accept more it would be great.
[REL] Releases only, followed by version number if needed
[WIP] Works-In-Progress
[TUTORIAL] Obviously tells someone else how to do something(i saw this today and its a great idea)
[HELP] or [
] Someone has a question
this might seem kinda over the top, but it lets you find what you want at a glance, without digging through all of the threads. just a suggestion.
