Well, I personally don't like Eberron. Don't much care for changelings or warforged. That being said ...
I would be willing to DM a solo game. I am preferential to my Hombrew World of Enigmatica. Interested - see the link in the Sblock in my sig. As far as recruiting goes, I'll give Kaodi preferential treatment in enlistment. But if the interest isn't there and someone else is interested I'll take that into account.
World Info (and very basic maps) are in the link in the sig. Anyone interested, I'd really prefer that you read through enough of one or both of the games that I DM just to get a taste of my DMing style. If it is a solo game ... you'd best like my style of posting. I'm not trying to bring glory to my games, just want to make sure you like how I post.
If you are really desiring to immerse yourself into the game world, feel free to read my Story Hour (link also in the sig). The Story Hour is heavily draconic in theme ... I like dragons

... and what they can do to a world.
As far as posting rates go, I guarantee one post a day, but I log in as much as 5 to 10 times on a typical day. In a solo game, I guarantee that if the player posts, I'll post when I next log in. I post from Eastern Standard Time Zone, for what it's worth.
Anyway, thought I would offer.
