I've heard of bottler but I don't know what it does.As for the addon you mention, it doesn't look all that trustworthy to me. mIRC, like anything, can only go as fast as your computer and the 'Net connection will allow it so claims about an addon making it all go faster seems a bit iffy to me. I would be checking to see what it does, and I mean from the first line of code to the very last, before installing it.
