vBulletin Membership Subscriptions!

[imk]

Ok guys so one of my forums is opening up a private forum and i want to be able to use recurring payments.

I know vBulletin has it's own inbuilt but i also want to offer a affiliate program.

Those who have already done this what do you use? Something like 2checkout or plimus i guess?

Also should i be using amember or is vbulletins subscription good enough?

I basically want to open the forum and allow affiliates to push memberships for a commission!

thanks
