First off, I'd like to apologize for not getting to answer you sooner, I've been rather busy lately with paid work.
There are some of the prestige classes that we couldn't find in the Forgotten Realms one.. we were talking about making them. If we do, would you like for us to give you the data to add to yours?
I'm not a big fan of prestige classes personally. I will get to them eventually, but you need to be careful with them. In particular from Forgotten Realms, many of the Prestige Classes were revised for 3.5 in the Player's Guide to Faerun, which replaces older Prestige Classes. I'd only be interested in Prestige Classes if they are the updated versions (or original if there is no updated version that replaces them). Submit those to me and I'll give you credit for adding them. Make sure you test everything and that they work correctly though. The reason I haven't gotten to them yet is that they are very time consuming to do. Each prestige class takes me between 1 hour and 2 days to code to be honest. Some of them are quite complex in the conversion process.
Also, for Dragonlance will you be adding the various sects of Knights as prestige classes? I'm only asking because we want to try to make Lord Soth for the group to fight against and be able to make other Knights to maybe help the group.
I will be adding the data as it appears in the books, I am starting with the Dragonlance Campaign Setting and am planning to tackle War of the Lance immediately following that work. Other books will be added as time permits once I get the basic material done. If it's in the DLCS book, then it will likely get added as I get time to do it. (The knightly order Prestige Classes are if I am not mistaken in the setting book.) I will say this, I am trying to get the data released soon, so the PrC's may be missing in the initial release, but they will appear in a future update when I get time to add them in. One thing to keep in mind is that I have to hand type all the material, it's not copy/paste from pdf files so it will take a little more time to get done.
