Hello!
I am sorry if my topic isn't in the required forum, but I don't know where to post it.
Well, I was wondering with myself; what are the channels?
When I wrote #3 hi in the chat box, it says: "This channel doesn't exist"
Help me please.
Thank you, my gratitude to both of you.

i'm also interested what are the channels , and you can also type /join and then something and it will say this channel doesn't exist.

Hello. As far as I know, the channel are special vias used by the helpers for comunicating with themselves. There is a channel named "helpers"; OK, I don't remember what's its name since I don't type such commands since some months ago, but once I entered that name and I got an information in french saying that I can't use the channel. Best regards.
