I'll echo the comment above and say that I was so happy to find out that there was a whole community of Snupin shippers out there and that it wasn't just me! I joined up at the snape_n_lupin Yahoo Group years ago, and after the mailing list had become mostly inactive, I was thrilled to find this comm over at LJ (and now IJ).
One of my favorite Snupin memories is the Trading Places challenge. It was the first fest I'd ever participated in and I was kind of nervous about it, but I really had a lot of fun! My icon was taken from the beautiful artwork that karasu_hime made for me for that challenge.
