webchat addresses have been banned (for now), due to a terribly annoying troll, download a client, there are some guides on the wiki. You also need to register an account with freenode.
for me it says " you are banned" and as far as i am aware i have not done anything to warrant a ban EDIT: 1. how do you make an account on freenode? 2. How do you download it on their website is just links to donate and about them and a load of other rubbish like group channels and stuff
@burning97 actually webchat addresses are not banned anymore, you have a ban from catelite, was probably that other troll on your ip, as for @spektyte, i don't know why.
i get this [23:48] == gateway/web/freenode/ip.__________ is now your hidden host (set by syn.) [23:48] == #powder Cannot join channel (+b) - you are banned
