Kiwi IRC is a webapp for IRC.
I thought it was quite popular as it's been around for a couple of years and feels very slick and professional but there don't seem to be any previous questions about it here.
I know there is a standard IRC command
/server to connect to a new/extra server.
But what about when you've finished with one server and want to close it but keep any others you are using going? I couldn't find anything in Kiwi's docs or by googling to see how to disconnect from a server once I'm done with it.
