I'm not sure if this has been pointed out yet, I may have missed it, but the forum structure is basically upside down, a relic of a time when this was the "Technical" TW forum.

So - basically, the social forums, Frontroom, Backroom etc. should be at the top under the Entrance Hall and Watchtower. Everything relating to specific Total War games should be below that, then forums for mods, then archives. Currently you have to scroll all the way down to the Backroom, past the completely dead Warhammer forums, past the huge glut of archives, to get to the social forums where the activity is.

Right now the site looks dead.

Aside from that, I'd break the game forums up by era, so all the Classical games together, all the Medieval games, the Shogun games, then the Early Modern ones. Warhammer can go at the bottom as it has generated the least interest.

In terms of content - something like Frog's unit guides would be a good shout. I'd be willing to do the Roman Factions for Attila for a start, go through all the units, give stats, some opinions on use, add a historical not here and there...
