it's all good just trying to figure out why some have the privileges to upload files and delete posts within 30 minutes of posting if no replies. But thanks for the "support"
If you have earned your Veteran's Forum trophy (skill 300), you can delete any thread you created here. If you have trophies for all forums and have completed the quest for the Admin's Prize, you get a red forum name and the ability to delete any thread anywhere. As a bonus, you get 3am wakeup calls to post messages about servers being down.
Why would you care about deleting your thread? If it's something you realize you knew or didn't care about, it staying on the board might be a learning experience for others. Just move along. Move along, move along.
