Hi there! :)

First off, I just have to tell you that this post makes me very, very happy. ^_^

Second, I haven't explored much of the Avengers fandom on LJ, but there is in fact this community: clintcoulson From what I've been able to tell though, most of the decent Avengers fics get posted straight to AO3. I've started following the pairing tag there just because it's a little easier for me to keep track of. If you're looking for some Clint/Coulson recs, I'd start here; there are some really wonderful things listed, and the person who created the list is also a terrific author for the pairing in her own right.

I hope this helps!
