You probably aren't responding to -host on the account. Note that this
uses, by default, a preference for the account:

/*!
 * @brief Connect Host
 *
 * Convenience method for retrieving the connect host for this account
 */
- (NSString *)host
{
	return [self preferenceForKey:KEY_CONNECT_HOST group:GROUP_ACCOUNT_STATUS];
}

This is used to determine connectivity, you shouldn't need to add that
to the init. When the server specified by -host is available, it will
connect. See also:

This is probably related to #1/#3. If it doesn't fix it by returning a
-host, please respond.

It might be, I'm not all that sure I understand. Does the checkbox not
work, or is it merely not connecting? The initial connect here, that
is when enabling, probably requires the host be connectable, so #1
applies.

The window won't shake. You should be posting Chat_NudgeBuzzOccured like so:


[[NSNotificationCenter defaultCenter]
postNotificationName:Chat_NudgeBuzzOccured object:chat nil];
