You can't just yet. I am working on getting it coded into the stats page, but haven't gotten around to it yet. Been pretty busy this week. For now, just look under the worker stats tab at your shares compared to everyone elses and you can kind of figure out how much of the 50 coin reward you're going to get. Blocks are going so fast for this coin, it doesn't really make a whole lot of sense to check your balance anyways. Payments were sent out from the first block found already.
