PS: Don't forget to open source it.
Here's another, also in Django.
There's a download here: http://code.google.com/p/cnprog/issues/detail?id=28
but I don't think it is production-ready yet....
I'm aware of the chinese solutions done in Django but after looking it over, I think I can do better.
I'll prolly write it in PHP too (gasp) so any n00b can basically rip it off and throw it unto shared hosting! ahh, gotta love opensource =)
Weekends plural? I thought this was only going to take 1?
