First of all, we have a distinct bug tracker for posting any bugs. It's here: http://code.google.com/p/joomlaworks/issues/list
Secondly, I doubt the "several bugs" you mention have anything to do with K2. K2 is a solid content platform for Joomla!. If you are a newbie with Joomla! in general, I'd suggest more trial/error attempts if you don't want to wait for someone to answer to you in the forum.
K2 is quite popular, so some posts may skip answers. But that usually happens to posts that are already answered and the posters are really bored to run a search before posting...
