Any good FAQs for modifying the NCBI blast codebase?

[Michael DiBernardo]

I'm interested in messing around with the code that implements the blast
algorithms (specifically some of the psi-blast stuff) in the NCBI sdk
distribution, but the documentation is outdated and I'm having a bit of
trouble getting grounded. Does anyone know of any good FAQs or
newsgroups/forums where discussions about this sort of thing take place or
have been recorded?

Thanks,

-M.D.
