AutoReconnect

Misc > AutoReconnect auto-joins the server for you if you were disconnected for any reason.

.autoreconnect enabled <0/1>

.autoreconnect delay <seconds> - default 5.0 - wait delay between reconnect attempts

Hint: Setting this to e.g. 4.0 will likely put you ahead of other players with AutoReconnect who run with the default value! Please don't go crazy as it may lead to all sorts of problems.
