As yet another update to the web chat situation, the web client now lets you join and watch the action, however currently (until July 5) you will need to ask an op to get +v set so you can speak. On July 5, we're transitioning the channel to such a state where you will need to log into freenode services before you can enter the channel, but once you are logged into freenode's services, you should be able to join the channel without any problems from any client.

Also: shell accounts on tacgnol are still available for anybody who just loves having shell accounts.
