Just wanted to say, very much love the work and care you've put into the Codex. I originally was doing very similar work, myself, for an adapted E-8 system mostly due to the fact that I felt that 3/4 BAB classes were left behind too much compared to pure martial ones.
Your solutions with the signature and epic feats is very organic, and to be honest, addresses just about every issue I previously had with the limited BAB for 3/4 classes. I also really like that you allow them to tap into 3rd level spells, and Rangers/Paladins into 2nd level spells, in a system similar to the one I'd envisioned but handled very elegantly. It's a great resource, and one I'll definitely use in the future. Looking forward to the unabridged version. Totally using this if I ever DM again.
Will definitely offer some help there, if I'm able, in proofreading and the like. =]
