Post here if you're bringing someone along!
In the interest of keeping a semi-accurate head count, it'd be swell if we could compile the Plus-ones in a thread of its own. So if you're bringing along a friend/spouse/SO/whatever who does not have their own MetaFilter account, post here. Since Metafilter doesn't have editing or deletion of posts, if you're unsure, take your time, we don't need a final head-count for a while.
Again, this thread is just for tallying the "extras" that the normal attendance tool doesn't capture.
