When successfully bound/integrated with IPB, are there options to change the user's group upon successful purchase?
have a look to aMember CP -> protect Content -> Integrations. You can assign each IPB group and specify when it will be added.
There exists, currently, a Default group that someone "returns" to if they have no active subscriptions. Is that worded correctly? My intent is to mirror current functionality, which is: I have two forms of non-paid member. I have the "Guests", which would be default, which are people that are new to the community, generally unproven individuals. When they have been around for a while, a moderator is able to promote them to "Member" - which just says someone is not new. However, at any time, someone can go in and purchase a Donor subscription - lasts for a month, for as long as they feel like continuing to pay. However, from the wording here, it seems that if someone were to let their subscription lapse for any reason, they would go back to the Default group, which is below where they ought to be. Is that correct?
