I would like to thru out an idea out there where the auto message plugin can be transformed as one of true useful marketing solution for WP.
1. Integrate it with pro sites and can read the levels as "categories" for sending messages. e.g. if someone signs up as premium, besides sending them the same messages over 30 days, i can "tag" or "catogerize" the auto message to match whether they are free, pro, platinum, all etc.
2. Same as 1 but also integrate with the default WP roles. This may also be a further categorization.
Actually #1 is my main request/recommendation. This will really allow us to send messages base on the pro site levels so we can fully automatic the marketing aspects of pro sites.....
