Sorry for puting it in this thread, but there is a problem (either on my side or yours). See bellow:

Hi Michel,

Ok, first of all, when I tried to create this message in UT Related category, it gave me wrong list of categories (for C forum, it looks like)

I also have a question: Is it possible to retrieve all messages for the particular forum for the particular category (Right now I need all messages in Chatter/Puzzles category).

Thanks in advance.
