'Free' Membership? Do you need to activate a payment gateway?

Hi there

I'm installing the plugin on Buddypress, it's working fine - truly a great plug-in, thanks - but the one problem I am having is that the user isnt able to select a subscription pack when signing up.

I dont want/need to charge for sign up but looking through all the documentation it seems like there's a need to. Is there a way to offer a subscription without configuring a payment gateway?

Also, a couple of more Qs: Are you able to automatically add members to levels or does this still need to be done manually? Lastly, the plug-in mentioned somewhere that there's a login re-direct so users automatically go to the activity stream?

Thanks
B

Update: I've found the Free Subscription, thanks. That's that sorted, would be great if anybody knew the last two q's answers though
