The topic calls this the social solution for m:tg players but I can see a problem:
Anyone who has difficulty distinguishing reality from fantasy should NOT use this service.
Also:
Why would I want an Imaginary Girlfriend?
Good question, my friend. Good question. I often wonder why I even want a
real one

Hmm. This could be better than I thought:
Do I have to write back to my Imaginary Girlfriend?
No! You do not have to write back or acknowledge your Imaginary Girlfriend.
Nice.
[EDIT]Damn. All the good ones are taken.
