LJ community search

Am busy writing with really not much to say, only that I've got a title for the new fic! Am still only squinting at the flist for lack of GoF-seeing (tomorrow, *bounces*).

But could someone perhaps help me out? I just spent half an hour searching for the LJ Community that people post a notice to when they've temporarily deleted their LJ? I *know* it exists (or has, half a year back), but no idea if it's LJ-wide or HP-specific... Does that ring anyone's bell? Gah, I feel so stupid.

ETA: *hugs* mizbean and bookmarks for sure this time*
