It would be helpful to have 1) a timestamp attached to each invite referring to how long the invite will be active on the Manage Invites page for sellers to see, and

2. a expiration timestamp on the invite on the Invites Received for the buyer to see (I don't have any active invites open so I'm not 100% sure this is needed, sorry!)

ALSOOO most people redeem CW invites immediately, but sometimes invites are missed for whatever reason. An automatic reminder sent 48 hours before the expiration of the invite would be awesome in this case!
