A few Request for Features

I have a few request for new features that would be valuable to my group:

1) Can we add a feature where I can send an group e-mail blast to only those folks who have RSVPed for an event?

2) When I add photos to the photo gallery, can I have the option to have it appear under the "Recent Group Activity?" That is, instead of an automatic post of the person who posted the photo, I would rather have a thumbnail of one of the photos I posted to the gallery appear in the "Recent Group Activity" area.

3) I tried to put a image link in the summary area that would post a photo from the photo gallery, but that does not work. Having a small photo from the photo gallery appear on the Summary Page (which I can change periodically) helps members see that events are constantly happening.

4) I badly need a payment mechanism, such a paypal, where I can list the cost of an event and so that people can pay for listed events. I tried to insert a "paypal" button, but paypal seems to provide it with a "Forms" tag, which collectivex does not support. Any ideas?

Thanks,

Roque
