otaku: There is a documentation file that comes with MultiHack that should help you with most questions. The documentation I admit isn't the greatest though, as like most programmers I like to code and hate documentation(unless I need to read it of course). heh
If you have questions though about it you can ask them here in this forum or on the MultiHack web site forums, up to you. I and others will do the best we can to help you.
It is fairly straight forward if you have ever followed the hack directions manually.
