No way to stay updated via email so just watch and wait I suppose.

If you want to help the dev get more recognition for Powercoin, I'd suggest everyone takes at least 5 minutes to raise some awareness in some way - submit to an exchange, tweet at the exchanges, talk on the trollbox of current exchanges (which I might add, seems to influence a couple of purchases at a time for just mentioning it), or something else, but don't just sit on your asses.
