Dev's & Others ?

here's some more recent coders that I know of;

KLS
WildcardX
Bleh

Also, Cavedude is now in charge of the whole PEQ database project, and has pumped "new life" into it.
You might want to visit the PEQ forums and get some history there. Don't forget Sesmar Alaharnok and his http://eqemu.sesmar.net/ site. this is probably the first place where database were public available for download (Cavedude's Installer and the EQ db.) I always said "EQ database is the grand-daddy of them all".
You can also see a lot of history in the EqEmu changelogs at http://eqemulator.net/download.php

[cavedude]

tcsmyworld for database work. He actually created the first database with moving mobs. Back in those days, all the grids and spawns had to be put in by hand, no automatic tools like we have now. He's also a current member of PEQ.

Before him, drawde was responsible for a lot of the very very early db work.

Here is also a list of Quest writers on PEQ (please note, these are PEQ forum handles, and not EQEmu):

I don't know if this is relevant, but there were some people that didn't have coding, or quest writing, or db skills, but they helped many people just lending support in setting up the emu (back when it was kinda' tricky). I don't know of names atm, but I will look up some if you think they should be mentioned also.
