They should be removed, yeah. I reported some stickies that were old and from a forum called Market Swag which TE merged here and they were un-stickied, so just report them as Other or something, Staff are intelligent, they will/should know. (Unless Mike answers your report)
Guess I stepped down in the wrong time for Runegear =P
Grumpy yea just report the posts and eventually they will get unstickied or w.e
Just like any other post that is in the wrong section Just report them =)
