From the description it sounds like you were looking for Ema's Spell Sheets. Is the attached wizard spell sheet what you were thinking of? Unfortunately Ema's site got taken down when he tried to branch into 4E stuff that bypassed the need for the books and WOTC stepped in. It's too bad, because the 3e stuff was still legal by the OGL (I think) and, as you've mentioned, very useful.
Anyway, depending on what kind of spell sheet you're looking for there's a good chance I still have a copy. I saved several complete spell/power sheets from the site if anyone is interested. Here's what I have...
- Auras - Dragon Shaman
- Infusions - Artificer
- Invocations - Warlock
- Invocations - Dragonfire Adept
- Manuevers - Crusader
- Manuevers - Swordsage
- Manuevers - Warblade
- Powers - Erudite
- Powers - Psychic Warrior
- Powers - Psion Egoist
- Powers - Psion Kineticist
- Powers - Psion Nomad
- Powers - Psion Seer
- Powers - Psion Shaper
- Powers - Psion Telepath
- Spells - Adept
- Spells - Archivist
- Spells - Assassin
- Spells - Bard
- Spells - Beguiler
- Spells - Cleric
- Spells - Druid
- Spells - Duskblade
- Spells - Warmage
- Spells - Wizard
Finally, there's also the Generic Spellcaster spell list- the generic class option from Unearthed Arcana which includes every spell from the cleric, druid and sorcerer/wizard lists. In case you want just a mega spell list.
If any one wants these, I can attach them here one at a time or try to find some kind of hosting solution. Haven't tried that before, so I'd need some pointers where I could do that. The total size for all of them is a little over 9 meg
