I'm tempted to go with what some people say here, I'm also a bit skeptical of this Crowdgather thing, but still... maybe we're just a bit too scared here.
Also, it does seem weird, but depending on who it is, someone who is here for just a few days might turn out to be more valuable than a long time member. I can take myself as an example, I'm here since 2001, and despite never having any warnings or bans, I do have a track record of screwups. That I'm here that long doesn't make me better, as much as I'd like to believe that...
(sidenote, 100x100 avatars would be great)
