Towards the end of 2012 Enworld was essentially destroyed by a hacker, and rebuilt. Most of the accumulated data from prior to that was lost...hence no die roller, change in forum layout, and so on. A lot's been restored since then and things seem to be chugging along just fine.
As for games I'm in...still quite a handful, if not so many as before.
There's a Numenera game called Center of Time that's looking good.
Selc Silverhand's long-running Wayfinders Eberron game.
Li Shenron has started a D&D Next playtest game called Dungeon Raiders.
Dr Simon has his Trefaldwyn Chronicles, a loosely historical take on D&D. He is also running a Keep on the Borderlands campaign, and a few others that I'm not in.
81Dagon has Wrath of the Righteous which is a big epic Pathfinder adventure path.
Airwalkrr is running the Pathfinder iteration of Rise of the Runelords.
Of these I don't know that any are actively recruiting, but you might drop a line in the various OOC threads and see if they're accepting applications. All of them are enough to hold my interest; your mileage may vary.
Scotley's got a Kingmaker campaign going.
