The remindme bot has a few interesting new commands I haven't documented yet. Easiest to do in PMs, but can be done in posts.

Think I'll do this in public as an example.

@remindme create public beacon MNDPUnderground
795085
@33MHz Beacon 'MNDPUnderground' created and subscribed.
795086
@remindme delete beacon mndpunderground
795088
@33MHz Beacon 'MNDPUnderground' deleted.
795090
795092
@33MHz Beacon 'MNDPUnderground' created and subscribed. /@darthgrammar @darkhawk @thedoctor @jdscolam

@darthgrammar @darkhawk @thedoctor @jdscolam now if you follow @remindme, you can PM it things like:

pub mndpunderground "this message!"

And anybody who subs that beacon will get a PM from @remindme.
