It would be great if there was a new node on this forum that had Big Boards as it's topic. I'm involved in running a couple of sites that can have a million plus daily visits, and a redundancy requirement that sees the xenforo software decentralised which leads to it's own peculiar set of issues, for example best practices to maintain code on numerous servers, mysql optimisation such as sharding. The impact of large numbers of usergroups and nodes etc. While I know that 99% of xenforo licencees aren't that interested I know there are some great people on this board who are involved with larger sites and I think we could all benefit by a bit of knowledge sharing on this particular esoteric aspect of xenforo. Plus you would hope that as Xenforo goes from strength to strength the number of people needing to get going in this area will only increase. Failing that, how about a prefix listing?
