Sorcerer 3.5 prc options

[mrcarter11]

Not having much success with the search function. Was curious if anyone could point me towards some sorcerer (or general arcane casting) prc options. Looking for homebrewed ones to be clear.

So, firstly going to point out the search I'm using to skim for some:

1. Clicked Advanced Search on the dark brown bar under the normal search field
2. Used the keywords "prestige arcane spontaneous"
3. Selected only "Homebrew Design" under "search in forum(s)", unchecking "also search in child forums"
4. Selected only "D&D 3.x class" under "search by prefix"

What I've turned up:

A spontaneous Arcane/ToB PRC for Tiamat worshippers (https://forums.giantitp.com/showthread.php?437711)
An energy-type-specific Evocation PRC (https://forums.giantitp.com/showthread.php?369586)
