Regarding the Min-Max/Deliberations issue I can see the following options then:
1)
Min-Max soley for the use of actual optimization. Things that fall into it includes builds, build requests, character/build advice(includes spell, feats, skills, races, equipment what have you), and discussions on optimizing builds/game mechanics. Simple Question thread remains as a specific exception, due to the required traffic volume.
Gameology covers GM advice and GM level things. Include game ideas and campaign settings(at least where they don't require extensive house rules).
House Rules covers new game material, whether rules, creatures, classes or whatever, as well as discussions on those areas.
Deliberations covers general discussions that don't fall under one of the above.
-This is basically the present state, with clarifications of role. No restructuring needed, though mods would want to move things like Endaire's threads where they belong proper.
2) Combine House Rules with Gameology. The rationale is a lot of these overlap. Both are largely GM side materials. On the plus side, theres no longer a conflict of where to place campaign settings. On the minus rules material are going to get mixed up with theorycrafting.
3) Combine Deliberations with Gameology. Don't differentiate between player-side and GM-side materials. Advantage is that most of these discussions are very very similar no matter what side of the table you're on and both are low traffic enough that there wouldn't be a big conflict of interest
4) Combine MinMax with Deliberations/Gameology. Its all D&D discussions, merge them all. Advantage is one less board to check for those frequenting MinMax. Disadvantage is that MinMax traffic would very swiftly drive those threads into oblivion as they ram up against the 10 new threads each day(though granted, asking similar things for the most part).
I can see some perks to 1+3, but favor the status quo(that is, 1) with clarifications. Most members post everything in the right places anyway, except for a few persistent offenders(and THAT generally annoys minmax when irrelevant stuff gets lumped in).
