"Events" for checkouts.
It would be nice to be able to create an event and then manage things per event.
For example,
We have two guys on a video shoot, each with checked out equipment.
It would be nice to see in 1 e-mail, the equipment checked out for that event, and who has it checked out.
It would help with keeping things organized in that, I won't get 30 e-mails when someone checks out something for an event. (Instead, i will get 1 e-mail with the event, and all the items checked out for it.)

I’m marking this complete since we support custom alerts as well as daily email digests

A few of your messages got tagged as spam by uservoice, and so I'm just seeing them right now.
This is a fairly old message but just incase you havent seen the feature, we allow for message digests now -

Also, my company just blocked/flagged your e-mails as spam because i was receiving so many of them...
Maybe rather then sending them medially just pool them into one e-mail...
