Improved email system? Right now it's basically "Delete after reply" and you have X number of messages when you log in (doesn't distinguish between you having read them or not like it does for the comm post). An index list would be nice too.
Since this is going to be a standalone game all the communications are going to have to be improved.
At this point they'll probably stay similar to the way they exist in OOII. However at some point I do want to revisit them and make them more robust.
