Development team active in Slack, but also needs communication in the Bitcointalk Forum, there are more members here.
I'm not on Slack, what do you mean by "active"? Still no activity on their github account at https://github.com/siriuscore/sirius , for 6 months now, except some tiny cosmetic changes 11 days ago. As predicted, I think this coin is dead, with the price now much less than half when it was listed on Cryptopia, and last daily trading volume of 0.07 BTC per day. It is like penny stocks now.If you think is dead, i advise you to sell everything and move on while you can still make something out of it.
