Sadly, I had to ask Best Beloved to find out who Rachel and Chandler even were, so no. And I can't even think of a community that might help you out there.

My fault entirely. I was so engrossed with them I actually forgot someone might have not watched Friends. This is not the first time that has happened. :D
And yeah, there really isn't comms for them. I found one for Chandler/Joey slash, but sadly that's not what I want. It's really amazing how there isn't even one general fanfic comm for Friends.

I can't even find anything tagged Rachel/Chandler or Chandler/Rachel on del.icio.us. Wow.

I know! I checked it too. How is it possible? Or I guess it's partly because Friends was big before (and okay, after) fanfic came at least somewhat out of its closet. Though the rarity of it is still surprising.

Btw, that's a good idea for a community. I'd join.

Thanks for the link, I'll check it out! I hope it pans out, because otherwise I'll have to go back to ff.net and well, I don't wanna. :)
