I chose the name Deus because I use Domina Deus on the majority of my gaming tags, heh.
As for Rebecca... I guess everyone just calls me Rebecca, except my foreign relatives, who call me Revecca (which technically is my name). I dunno why, just never used an abbreviation. I have a long last name (Greek names OP) so people usually use a shortened version of that for a nickname. ^_^
Thank you all very much for the welcome!~ I wasn't expecting so many posts!
