Both a reminder to myself and a hint to anyone else who wants to hack around...
|
||||
|
||||
* markov random chatter, add it back. should just need a thread and some polling
|
||||
* module unloading is *totally* busted. random objects disappear on an unload
|
||||
* some sort of cron interface (periodic events)
|
||||
* thinking about removing this, wouldn't crontab + XML-RPC be enough?
