Found that I was there already registered. But why? I don't like web-based messengers, they're too heavy to keep all online.

Why don't ITNS team establish a telegram supergroup chat? It doesn't have any ads and other garbage around the messages itself. It is light, fast and becomes more and more popular. Most of other teams have telegram groups (to name some, Bitcoin Atom and Coinomi).

I would suggest ITNS team to add a telegram chat to the media list.
