Any episode, I can't get anything! But since I have to be specific, episode 4.
Have you downloaded the program as modified by dythim? Are you in the K-F channel? Can you tell us where you are up to and what you have done?
Apis is a good bot to check out as she has every episode but she often gets hammered when a new release comes out. A list of everything on her is here http://apis.homeunix.net/apis.xdcc.list.txt so if you want episode 4, you would type /msg K-F|Apis xdcc send #4 (if you want you can cut and paste what I have just typed when you are in the channel. You can type the | symbol by pressing shift and backslash. If you want a different number then just check the list for the episode you want and the number on the left and type that in instead of the 4.
You will get put into a queue if all available spots are currently filled. Every few minutes or so a yellow line appears and tells you where you are in the queue and approximately how much longer you will have to wait.
When a new episode is released, one of the crew posts release triggers regularly to let everyone in the channel know what to do and which bots have the latest episode.
