No, but we are not really building parties initially. This is not a Player vs. Player format at this time either.
However playing an evil character with some good characters, might raise some role-playing issues in the long run. But for short term adventuring and testing of a character build, it doesn't matter to me. If I have a group of neutral and evil characters, I can work encounters to match that I guess.
I also don't have a problem administratively adjusting the Alignment later, so long as it doesn't break rules on the alignment dependent traits selected (i.e. the Cleric Domains). The nature of the games (not continuous campaigns) in this section are such that I allowing characters to be reworked in between adventures.
