MWPP Gen story - looking for archives, groups, communities

Hullo there! A friend of mine (the wonderful co-author of 'Call of the Wild') has agreed to let me pimp her latest fic, Stag Night, which can also be found on Fiction Alley, Stag Night.

I'm looking for MWPP-friendly (and James-friendly, Sirius-friendly, Remus-friendly, heck, even Peter-friendly) archives, groups and LJ communities. blackfall, you just hosted a Remus chat, would you happen to know where I should look?

The story is rich and subtle, beautifully characterised, and builds slowly. Set before James and Lily's wedding, the marauders, who have been growing somewhat apart since their school days, get together for James' big night. Peter isn't the only one who's keeping secrets...

EDITED: to add link, and move topic forward a day. CLS is just adding the finishing touches. This work is nearly complete.
