Thanks for the recent updates, there are a couple things I like to see for managing subscriptions.

a) When adding a receipt I'd like to be able to specify the start date. I would use this to handle subscriptions that come in from other sources (mail, active.com, etc).

b) When editing receipts I'd like to be able to change start / end-dates. This is to fix up imported subscritions.

c) I'd like the option for manually added or changed people to get receipts (like the notiification of a role).

d) I'd like the option to have a specific email address notified of new subscriptions and changes (so a membership person can do follow on).

e) I'd also like a second "reminder" type that could either be send manually of based on the amount of time since someone has logged into the site. I would look at this like the "probes" the listservs do to remind people they are subscribed. I would use this to remind people of their username (for manually added people) and to give them some quick hints on site usage at some defined interval.
