Mowgli,
For once, ENWorld is working better than Yahoo for me! My computer at work is screwy, and while I can see your emails, I can't reply to them, nor can I open the .pdf. So all of that will have to wait until tonight. But I'll answer what I remember here:
Thanks for everything you've done for/with/to Houwlou! I'm ready to play him and smite some gnolls and undead! (Houwlou can smell their gas from a mile away!)
Let's say Houwlou is 5'10" 165#. Languages -- I assume he gets Olcan and Common for free? Additional languages, I'm not sure how many he gets, bit the first one will be Gnoll, second elvish, third a foreign human tongue if we have one in the world that's in fairly wide usage.

I haven't looked at Aimhirghin's use of an action point in the game yet, but my understanding is that spending an action point either gives you ONE extra standard action in a round, so you can, for example, take 3 standard actions, 3 move actions, one move and two attacks, or cast a full round spell and take a move. I think that is right, but we'd better ask our resident 4E expert, renau1g, just to be sure. I do know that is you don't use your action points, then you lose them, but you also gain new ones at each "milestone," so, typically, a character will have one action point to use in nearly every encounter.
If you guys irritate me as badly as I think you might, I may start giving the monsters action points, too!
