Since it seems the forums I wrote these for, originally, have gone *poof*, I thought I'd link these here:
Base classes, more or less complete:
Healer, based on the JRPG 'Staff Chick' concept.
Psionic Sorcerer Bloodline
Hero, A very generic, versatile, and if necessary, simple to play, class.
Martial Monk, based more on actual chinese monastic monks of myth and fact.
Combo System, specifically designed to make warriors more awesome.
Musings on a Magic System, also contains notes on vancian magic and incarnum.
I'd be interested to hear your experiences, if you happen to use any of these.
