MQ scripts are so freaking easy you really shouldn't need a trainer.
Heck, take an hour or two and just read people's scripts. You can figure out most of it, and what you don't know just by glancing (variable handling and events maybe?) you can learn by taking an IRC scripting tutorial (
http://www.mirc.com , download that and just read the help files and how to script). MQ scripting and IRC scripting isn't identical, but they have the same retardedly basic structures to them. People in MQ aren't extremely mean or anything, I bet if you take the time and really can't figure something out, someone here will be nice enough to give ya an answer or at least a hint to figure it out.
I could sit down and write a ton of trainers talking about the aspects of MQ, but it's really a sort of waste of time. If you learn the structure behind basic scripting, you can look at just about any of the macros posted and learn TONS from them.
I'm not bashing you or anything, I'm just telling ya this isn't rocket science and you can learn it!
