That's unfortunate. It would be nice having another active reviewer around. Anyway, I've got a few requests I'm working on right now, but once I get them done, I'll look into reviewing one of those packs, probably Frags since that request hasn't been claimed by anyone.
The Flags pack is in Gnome's personal queue. He's been inactive long enough that I can pull the request, but I'd hate to do that only to have him turn up a few days later and say that he'd started a review a long time ago or something. Reviewing a pack takes a lot of time and I'd hate for him to waste it if he's still out there. That said, I certainly won't let the request sit there forever if Gnome isn't coming back. I'm just not going to pick it up right this minute.
