Der Brucer and I could pick out the initials. Since we're the ones doing the scorekeeping, we could pick initials like QZ, and make the work easy for ourselves!

More seriously, the current system, from our standpoint, works fine. Since der B is up way into the vampire hours, he can compile the list and have it up by the time everyone else awakens, so they don't constantly have to plow through the posts to avoid repetitions.
And keep in mind, everyone: There are some names, with every set of initials, which are obvious. These are going to be the first names that come up, and probably would come up no matter who made the first dozen posts. I suppose those first posters could refrain from posting the obvious names, saving them for later contributors, but then someone making the next dozen posts would pick them, or the dozen after that. Those names are going to get posted at some point.
The trick is to come up with names that no one else has thought of. That's the game. And, who knows? Maybe you'll come up with a name that no one else knows, but in also telling what that person does, or has done, you'll help someone discover things they never knew before!
That's what I call fun!
