Hi, I would like to ask a few nooby simple questions about vJass because as far as I can see, theres no page just giving lots of info about it. and vexorian never explains that much... Or just say im stupid and redirect me to a tut 
1. I don't understand how other war3's on bNet can play vJass. Wouldn't it be a foreign language to their warcafts?
2. Can I still keep the GUI i already had on my map if I start using it?
3. can I still use Jass stuff, it doesnt have to be vJass all the time?
4. and has JNGP been updated to work with the patch?
If most of this are answered positively, ill become a vJasser
