Subscription settings problem

[sarkar]

Hello all,

I have a board on which I have a group called Friends, where I used to add some special ppl, who helped the community. Now I wanna move all of em to a special group called RA Group (Resource-access) which will give them access to my PSD resource area. Thats a subscription group and ppl can pay and access. How can I set all of them to my one month package from today's date so that after 1 month, they are automatically moved to the normal group (members)

I have around 75 members, which one by one moving is pretty difficult. Please help accordingly.
