Membership Levels

Question about purchasing membership and when it expires.

I have a special membership called verified.  When someone verifies their membership, they are upgraded from standard to Verified.

If they purchase a Bronze membership (30 days for example) and that expires, I believe they are going to go back to standard.

I need to know how, when a purchased membership expires, it goes back to the original membership they had when they bought the upgraded membership.

I think I'd have to add a field to sys_acl_levels_members called 'previous_membership'.

Then store the membership ID there when they buy the paid membership.

Then when that membership expires, it downgrades to the stored value.

Unless Dolphin does this already.

Thank you for your time.

I have asked something similar about if someone has a membership that is yet to expire, and they purchase a higher membership and I manually set their membership level to that one, what about the old current one that had yet to expire?  Got no real answer.

In other words, hopefully the answer here will be more about exactly what is going on with memberships, which tables are involved, how the whole thing is suppose to work and did Boonex think about all the scenarios; such as one buying a new membership level but not wanting to wait for the old one to expire and asking the admins to change it.

My thought is that it should return to the previous membership, either to full fill that obligation, or as in my case, a special membership they are granted by becoming verified.

Nobody has any idea on how to accomplish this?
