After examining the actual number of function-related threads here it seems like there's really not enough traffic with that specific subject to justify a separate area at this point. It is easy enough to ignore function-related threads here, and not difficult to find them should you be particularly interested.
Furthermore it may be difficult to differentiate a function-related thread from a "normal" one in many cases as the functions are not necessarily separate from the other nodes and they in fact work only in combination with them. This would be an issue both for the original poster and for the moderators. Threads also often drift off their original topics, which could cause further confusion. I'm sure everyone would agree that creating a distinction and then not actually seeing it realized in people's posting habits would not be advantageous as people would look in the expected place for function information but not find all of it.
We can consider adding a custom message icon for functions (see the top of the Post form), or people can use a prefix such as [Functions] on their posts if they desire, but ultimately further fragmentation of the forum at this time doesn't seem like the best solution. We will continue to monitor the amount of function-related discussion and will reconsider this in the future if it becomes needed.
