In my most very humble opinion (at least as humble as any cat could ever be), it is an oversight of the grandest proportions that probablamenteno and Jerdge are not already in there.
Anyway, a few of those that I wanted to nominate have already been, allowing me the opportunity to use 5 noms on those that have yet to be. Therefore, in the interests of avoiding redundancy...
My (om)Nom nom nom nom noms (in alphabetical order):
Azure
Fodell
Jericthegreat
LastoftheRomans
Pippedy
(As an aside, while I am truly honored by the nomination, I have done nothing (yet) to warrant being included in any Hall of Fame, let alone the GPA's.)
