I'm trying to access an IRC channel on FreeNode.
I can only access to some IRC channels, but not to all of them. For instance, I can access to
#wikipedia-en-help channel but when I try to access
#github channels I get the following message:
Cannot join channel (+r) - you need to be identified with services - see https://freenode.net/kb/answer/registration
I'm on the website https://freenode.net/ but I don't really undesratnd how to register or identify myself.
How may I solve the trouble and being able to use IRC chats?
