I also had a problem in joining Slack. I'm hoping I can join because I need #nodesharring and in the iota.readme The suggestion is that slack is where to find Node Sharing Partners. It looks as though I cannot run the program without mutual tethering. I would like to have an Iota wallet so that I can send purchases through better next to it for long term holding and use within the Iota platform. If there is another way to buy iota other than bitfinex please let me know.Thank You.
