Yea..unfortunately dev. hasn't shown up so that is the cause of price dwindling...If someone with good tech skills can help dev. or possibly take over until he is back that'd be great.
the problem is you need permissions for his github repos and currently only he has. otherwise id be happy to help out.
Create your own branch of the code on Github and work on that. Then we can all see the improvements you are making. If dev disappears (which I don't think but anyway) then the best code will become the main branch.
With Huntercoin the dev actually died, and at least 3 other developers have started their own branches of the code. In the end the partner of the dead developer will choose which will become the official branch.
