Multipool payouts are now been processed.
Links in the OP have been fixed. We are still working on windows wallet design.

Regarding Bittrex - I've tried to contact them yesterday but got no reply from them. Some pool owners were writing to me saying that Minerals will not be listed as they are strongly against us. I am not sure at the moment was is Bittrex stance on Minerals. Maybe we should try to get listed on Poloniex as well, here is the link to write about new coin requests: https://poloniex.com/coinRequest

Whatever the outcome of the exchanges is we are continuing working on the project - the next step is to organize SC tournament in a way that will promote Minerals. At the moment 100k Minerals for the tournament will probably not attract good players. We will first organize tipbot to promote Minerals among SC and other communities.
