I agree with roller in that we need to start buying things with Yac, instead of just mining/hoarding. I've put a link up on the website for bitcoinmegamart and also sent out a tweet.
In other news, Yacoin 0.4.4 has been officially released and can be downloaded from yacoin.org or github.
This release includes many updates by old c coder and the stake enhancements mentioned on the previous few pages by grokouser.
From here, we need to start thinking about what to do for 0.4.5! There are many interesting suggestions that have been made and it's time now to look into the pros and cons of some of them and decide what, if anything, to implement.
