Hello,
I just noticed that google is indexing multiple daniweb subdomains while searching for my sitename, sorry if it is against the policy to post a search for my site its hard to get the same result in google. This caused big google problems for an other site my company was develloping. Duplicate content penalties and stuff, we even lost the site from the index for a while.

My advice would be disable all the subdomains and only allow the ones you need.
Best regards ,
Remco
