Mainly, I don’t think that the community is large enough at this point to warrant such a thing, nor is there enough diversity of membership at the moment. In order for such a forum section to be viable, there needs to be a much broader base of active members, both as individuals, and as businesses (corporations, firms, etc.), each of which needing the services such a forum section could provide. Now granted, the membership here at chatbots.org numbers in the tens of thousands (over 54,000 when last I looked), but the number of “active” members (those who post at least once per month or more) is in the range of a few dozen or so (certainly less than 100).
Now please bear in mind that this is just my opinion, and doesn’t necessarily reflect those of anyone/anything else beyond that, and I willingly admit that I could be wrong, so take my words with a grain of salt.
