There is a Slightly easier way to use mIRC xdcc bots. Goto
http://www.ircspy.com and just type in the search what you're looking for. It'll list all the bots available and you just click one cntl + v
*just right click and paste the command has been already pre copied* in the channel window and your good to go. This site does not list everything out there. It still doesnt beat going to the channel and actually looking up the bots, but if the bots have been listed it does help. Also since all the anime groups on IRC are still kinda messed up im not sure how much stuff you'll be able to find.
