[GeneX-dev] Re: Performance, development, schema, etc

[Todd F. P. <tf...@nc...>]

Dear HIlmar:

Thank you for your interest in GeneX. The project has been semi-dormant
for a while, but is now active again. I will respond to your questions
after a bit of research. Problably will have answers tomorrow. Thank you
for your patience.
