I've always wanted to do a collab but never got around to it. I'd be interested. I haven't read your stuff but I'll be sure to check it out soon.
You can look at my writing. I think most of it is pretty good if I do say so myself. :Pbut a lot of it is frerard.
Let me know if you want to write anything though.
You can email me at firstname.lastname@example.org
