That's are really good news. However, I would wait some more time until a real progress in code is confirmed. From my experience, the return of main developers is not enough for a 100%+ price increase.

Then combine that with efforts to improve other aspects of the project from within the community i.e. instructional videos, graphics, GUI etc., then there has never been a better time to take up a position in Boolberry. The success of a project shouldn't wrest on the shoulders of one person but instead upon the entirety of a proactive community.
