help for membership levels

Hi,

Can you tell me of upgrade a level for more than 30 members in one time ? because i loose my time if i must upgrade one member to one member.

It's possible ?

And can you tell me if it's possible of use automatically my memberships levels direclty and not the default Boonex standard or promotion membership.

I have see what this is not possible of cancel or remove Boonex system memberships on the boonex interface but if you have an idea....

if you are needing to upgrade more than 30 members, then your most probable best solution would be to hit the database. 

as for your second inquiry, im afraid that the standard will always be there on the current version. you dont have to use the promotional, but the standard membership is what it resorts to on membership downgrade.
