I've been away from the CNCzone for a while and I was really surprised to see the number of separate forums that exist now.
Before the CNC zone we were limited to more simple forums such as CAD_CAM_EDM_DRO on Yahoo and I think the zone has surpassed these in popularity and also usefulness.
But I cannot understand why there are for example over 40 forums on CAM. Granted there are more than 40 pieces of CAM software but most of these forums have less than 50 posts. It would make much more sense to have the general discussion forum, then a few forums for the most popular pieces of software. That way those using less common software will still have their posts read by those reading the general forum. Let us not forget that many issues are are actually quite general when it comes to it.
And I think the same is true for the rest of the forums, I am sure that someone experienced in CNC could answer many questions in forums about software and machines he/she has never seen and if not answer them learn from the answers others give, at the moment it is impossible to even browse the forum lists because they are so long.
It is always possible to classify and subdivide further and further but I think this can be bad because you lose the cross pollination that is so important to problem solving and learning.
