I'm normally online as Igor2 between 5:00 CET and 19:00 CET; on Sunday there's an AFK-window between 11:00 CET and 16:00 CET. If I don't answer in a few minutes I'm probably away doing something, please be patient; say hi before you type your long question so you see if I'm available.
Below is an iframe of kiwiirc irc client configured with the above settings. If it doesn't work, please visit their page and try to manually configure it, it's just 4 fields.
Connecting with the web client may take some time, give it a minute.
