When a user joins the help channel they will get a greet notice of the bot telling them what to do if they need help.

!chanserv lists chanserv commands etc
!nickserv lists nickserv commands
!memoserv lists memoserv commands

I haven't included every command, I have just included the ones that I personally think are most common.

**I know I could put this in a txt file and /play but I chose not to***
