Yeah I am running the exchange. :) Hmm, I hadn't thought about running it through AO3. I think I want to give Tumblr a chance first, since I'm more familiar with it so I'll do a better job, and I think it's more suitable for sharing multiple types of fanworks like art and gifs and such. I could be totally wrong though, and I will definitely consider running it through AO3 if running it on Tumblr doesn't work out. I might ask you for advice if that happens since I don't know much about AO3 exchanges :D

I thought a lot about your advice and I will definitely keep it in mind. Thank you so much for the idea and feedback, I really appreciate it!! :)
