Sounds like a good idea. However, I personally think the ZUG forums could be put together in more general sections. I already think there are too many subforums, and when there are going to be 2 or 3 Simpad sections added, it becomes a rather unpleasant browsing experience, having to read through all the different sections.
With the amount of topics being opened, I think it can be justified to make a few rules about having to clearly specify the hardware and software platform, and put them in more general sections. Now I see myself scrolling through the forums that particularly interest me, while topics that might interest me (or more importantly, topics in which I could provide with help) that get posted in, say, the C3000 forum or the 6000 forum, never get read because they're in a subforum that doesn't draw my attention (I own a C860 and are therefore particularly interested in that model).
A lot of topics that get posted to a specific hardware (or software) platform actually apply to the other platforms as well.
I'm specifically suggesting that the different models (or series, rather: 5x00, 6000, C-series, and possibly Simpad) get one subforum (instead of 2 currently) and be put in some sort of "models" subforum. Due to the developer forums being rather "slow" when it comes to new posts, I think it can be justified to just make 1 "developer" forum as well, and maybe have a set of rules about clearly defining a topic.
Though I can see the need for a forum for unregistered posters, having 2 general discussion forums for me (and I'm guessing other people too) means I have to browse through 2 different forums with generally the same content. This also makes it hard to remember where to find some topic you were following.
The newbie subforum posts would fit just fine in the other technical support forums, the difference between newbie issues and "hardcore user" issues is often ambiguous. Again, the amount of posts does not really justify a separate forum.
I realize this might just reflect my opinion and not the opinion of others, but right now I feel I have to click around much more than I would like, and more efficient and general grouping of subforums would make it a more pleasant place for me.
Maybe this deserves its own topic, but the perspective of getting 2 or 3 additional subforums for Simpad made me feel I should say this
