It's cool ... post a comment with a female character and people will reply and say nice stuff about them and post fic links, pics, etc.
There's a lot of characters already there. Chloe is here and I, of course, had to add Lois here.
And you can add more characters and even respond to your own threads. Nothing wrong with that.
Remember though, if you're responding for a character, hit respond, don't add a new comment. Just saying in advance.
Have fun guys!
