I got my first and only tattoos at Writercon 2004 - but I only found this link today:
http://www.fangedfour.com/tattoos/ People often ask me what my tattoo means. I am really glad I have it, because it reminds me of my fandom days and all the naughty fanfic writing I did back then. And it reminds me of the wonderful fandom that I was privileged to be part of.
I also saw that Writercon UK has a facebook. Man, I really am in a nostalgic funk these days...
