i like slack. i use it with several coins.
but with slack you need to open a new tab and log in, etc
this would be more simple, you would log in on the forums and you would have a chatbox right there. Like 38PTSWarrior said, our chat is dead.
in that new tab you can search chat history and share files easily. no need to hang around waiting to see if someone answers your question, just come back at your leisure and see if it was answered. announcements can be posted for all to see, separate channels for separate topics can be formed and and and....
but please, no chat in the client.
