Instead of just one monthly or whatever subscription payment and one trial membership option it would be nice to have more configurable options.
Firstly having multiple tiers that cost different amounts and/or are for different lengths, etc., would be beneficial.
Especially if we can have, for example, different tiers that have access to different stuff in the group/courses, etc.
Then having different options for creating length of subscription, wo that we could set up both a monthly and annual payment option for each tier, so we could offer discounted prices for anyone joining for a whole year rather than month to month. And also provide access to different stuff accordingly.
This would all also tie in with my other suggestion for drip feeding content and courses to group members based on how long they have been a member. (in this case giving them more sooner if they do annual membership, etc.)
