Thanks for the slack link. That's working. A touch of professionalism would have subtratum put the correct link on their site.
Why do they have http://x.co/SubSlack link on the substratum site (after you invest the link is on page that appears after you submit)?
Why do they leave a broken link?
Certainly not "FUDing" whatever that means. I don't have any tokens yet, and until now, had only their broken slack link.
If I get my token, then all is not lost.
