Alternatively, this link works as well: Mibbit IRC client widget And is probably easier than going through mibbit.
Has the mibbit chatroom been taken down? The link above has stopped working and it also appears not to exist on the mibbit website anymore.
I'm still having trouble accessing the widget ... seems like a DNS issue if it's affecting some but not others and will take a while for updates to propagate across the internet.
The link for mibbit seems to have disappeared again Edit: The link at the top of this page still works however
Yes, looks like the Mibbit Widget website is having some difficulty Down For Everyone Or Just Me -> Check if your website is down or up?
