I tried to post an ad to classifieds, but "no trial users allowed"; why's that?

As a Finnish boost enthusiast I do read a lot of forums, but seldom participate in conversation... Does the trial-user status change to "higher" grade when enough posts are written?

You know I am NOT going to chitchat some BS to get higher status...

 

You status will change in time.

 

All you had to do was IM a moderator and not post this here.
