I think it would be a good idea to have a Save button to save chat logs used on rackspace emails. Furthermore, I think it would be even better for users with multiple different emails types (rackspace, exchange, etc) to have a chat feature that speaks to each other versus currently, rackspace is the only email with a chat function and it can only speak to other rackspace email users.

It would be great if chat could be universal among the different email types.
