IRC: Cannot send to channel

Hi,

I used to be able to send to the #wordpress channel on chat.freenode.net but not anymore. I am a registered user (nddery), and authenticated. I receive this nice message “#wordpress Cannot send to channel”.

Like I said, it use to work, I don’t see why I would get banned, never insulted anyone or spammed the service…

Any ideas what to do to be able to send ?

Note: When accessing IRC from the from the webchat, I have no problem posting (authenticated as me – nddery)..

Thanks!
