The other day while looking for stuff I found a site that aims to archive any riffs to do with MLP.
I'll just drop a link to the place here.

752997 Oh my god, I have my own subsection. I has the happies.

I need to make a blog post. This site will get the promotion it deserves by the end of the night.

Time to submit some stuff, then.

Finally, someones keeping track of the things we do.

Wow, that's a thorough archive. It even has all of my guest submissions on there. Sweet!
