The last person I felt should be a mod was NEVR, and he is already modded.
I suppose Gagsy comes on here frequently enough, and is mature enough to know the site pretty much inside-and-out. She would be a good mod, since she is very unimposing.
I mean, Elios (for his thread-creating prowess), MissingNYC (for his general intelligence) and Corky52 (for his helpfulness) were at the top of my list at one point. Tramps and TehSlapHappy seem like favorites for modship at some point - they just need a few more years under their belt. Techno also could fit into that category.
Honestly - there are 30 users who just hang out in the Wi/Ht forum all day helping people, any one of whom would be an adequate mod. Frankly, I'm surprised that some of them haven't been offered it before. I suppose Coop would have been my first choice from that group, but he was modded, so I guess it would Bahamut, gfoxcook or Haggard as my next choices (just off the top of my head - I'm sure there are like 30 more).
