There are actually two of us looking to play! We prefer 4th Edition D&D, and I would prefer that the 'Power' books be allowed as supplements. Other than that, we don't have much of a preference.
We have both played 3, 3.5 and 4E. We've been playing 4E since august of last year, once a week. We do not mind hosting, although we do have a dog (she's crated during games). No smoking, even if we're not hosting, because of allergies.
