Well, while I've had 2 accounts @ ESF since c. 2002 (forgot the pw of the 1st one and the email addy registered under is LONG gone...(my old personal domains)) and registered a second around when Oblivion came out, but was dismayed by the new lows that the new "fans" that Oblivion brought with it to the ESF.
That being said ESF was never really anywhere that I hung around to a great extent, mainly just looking through the modding threads/info & pastt games forum, and occasionally through the general forums. In recent years, I've been around Prairie Games forums, and BC3000AD forums(yes, I do get some enjoyment out of Smart's Battlecruiser series, sue me...), and before then when I was playing ALOT of low grav TFC and DoD I was primarily planted @ Frenchy's Pit's forums, and also some, now defunct, Harpoon sites. But even above and beyond all of these web forums, I still, generally, prefer usenet newsgroups and mailing lists. (In reality most of the sites/groups that I DID participate in were entirely technical, e.g. FreeBSD, linux, mac fora, etc. but as there are not related to gaming, I will not list them.)
Initially, I must admit too, that I thought that the codex was a pit, however the realization of Oblivion for what it was(and was not) and the nearly total alignment of assessment of Oblivion(and other crpgs) made me reconsider the value of the codex, and so here I be. Also, I was looking for a decent RPG site, and didn't entirely care for just-rpgs growing console focus, nor entirely for the atmosphere of rpgdot/rpgwatch, rpgvault, etc.
