IPB has a feature called "clubs" - basically subcommunities - https://invisioncommunity.com/news/product-updates/new-clubs-r1017/
Right now, I have this feature disabled, but would this be something VAs would be interested in - being able to create a club within the phpVMS forum to post updates/use as a forum, without having to create your own? Similar to what avsim does, but there's a lot more customization. And maybe only for established VAs, so it doesn't get completely cluttered with one hit wonders.
Thoughts?
