Yes! I just received an email wondering if Open Admin was still 'alive'.
Yes, I am continuing development for many schools here in Canada, mainly including new features for assessment of student reading and numeracy. These include system for recording DRA (Diagnostic Reading Assessment), LLI (Literacy Intervention), PPVT (Peabody Picture Vocabulary Test), FSTEP (First Steps in Math), and have just finished starting applications for storing scores for a Common Math Assessment system based on outcomes from Saskatchewan Mathematics curriculum. (Add and View scripting only so far). I've also developed comprehensive scripts to evaluate all of these systems and track them for 20+ schools. I'm also in the final stages of development of compliance with the Alberta Education 'PASI' system for synching data with Alberta Ed.
As a result, I haven't had time to make a new release or update the docs for 'quite a while'. I do have an updated code base (which is updated as development proceeds), but updates to install scripts, etc. haven't been done (where necessary). Please let me know if you'd like the updated code base. I'll work on a new release for Debian Linux when a have a minute. If you need other O/S's, please let me know.
