Group Calendar for Buddypress: How Can My Group Members Sign up???

Hiya,

I feel silly asking this dumb question but I can't seem to find the answer...

I created an event in my Buddypress group. How can the members of my group sign up for it? And yes, I know I can invite them but naturally I want them to see the event and choose on their own without the invite.

Am I missing something??

Thanks,

DC
