I don't really like the r/l or r/t words either, but I use them because most people understand the connotations behind them. Online is real to me and you guys are all my friends, we just don't hang out face to face, or offline.
I like both of y'alls terms better, Mishka and tessa. I think I'll start using them. *smiles*
Oh and you and Rhabbi are really really sappy... but it's really cute.
