As far as anonymous posting in Orkut communities is concerned, You can post anonymously in only those communities that are of anonymous type... There's not way to post anonymously in non-anonymous communities.

I haven't noticed anonymous posting in vBulletin forums thus far. It might be so, that the specific forum has a provision for anonymous posting...
