One of the moderators should take a look at the forum and move those topics at a regular basis to the correct forum.
2. Topics in the MOD Add-On Forum (W/Code) are getting archived too fast. As a MOD author myself it's a pain to update a MOD and release a new version and you find the original topic has already been archived. It's also harder for new users to find MODs because they hardly look in the archives. Also, the last 4 topics (the content has been removed by the MOD author) should be moved to the archives or deleted.
3. The MOD Completed Add-Ons. It's not used by MOD authors, contains either outdated MODs or a dead download link and cause confusion (example). Not sure how to solve this though. I think it's not used by MOD authors because MODs are getting updated constantly and with a MOD posted in this forum you'd have to contact a moderator/admin to have the listing updated (would be a possible solution though having one moderator taking care of this).
That's all for now, I thought there was one more issue I wanted to post about, but I can't remember. Anyway, let me know what you think.
2 - When mods get old, they get archived. If your releasing a newer version, chances are you want to start a new topic to debug that version only, not the entire history of your mod. That way people arent sifting through 15 pages of old information just to get to the updated part.
I'd say either 9 or 12 months. Also, I think it would help if a link to the MOD W/Code Archive is added to the forum's description to make it easier for new users to find MODs.
