I think the forum structure is fine the way it is. Having another space for new user questions is going to create some confusion and may not serve everyone's interests.
I think that the description for the General forum can be tweaked slightly by moving the word "empeg" to the left. "General Empeg Discussion" seems reasonable to me. Of course I've never had a problem understanding the previous description and purpose of the forum.
The BBS growth has likely seen its peak. Everyone here now will get the hang of everything soon enough. The FAQ for the BBS is important to read, IMO and everyone should be checking out the FAQ at riocar.org. Next is the very powerful SEARCH capabilities of this forum. It works and it works very well. Maybe the BBS FAQ should be updated to reflect some of these suggestions and guidelines - maybe in a fairly direct way.
