@Prince: You can't by default, but you can look at a custom message system with that feature... you could've find that out by searching the forums, BTW...
@Kin: A guide on everything you can do with RMXP? What part of 'limitless possibilities because of RGSS' didn't you understand? XD Well, the events should be explained in the help file, and if not, I remember Raziel working on a guide explaining those. For everything else, refer to the help file or the FAQ.
@Nyah: You can't just learn from a single tutorial series... there are a bunch out there, and you also learn from just experimenting around. Set yourself a goal, and if you get stuck, try to work on your problem, as in 'why doesn't it work? - how can I fix it? - is there possibly an easier way?'... if that doesn't work (and this isn't like two minutes brainstorming - of course it consumes some time...), you can always ask someone around here... well, that's how I did it, and though I'm not a that good scripter, I can see myself making progress... and I'd consider myself far beyond the CMS level ^_^
