Just want to greet all of you. I'm a newbie here, so... welcome me!!
Looks like I'll be liking my surfing here. I see lot's of free downloads and tutorials available (right?)

Welcome Luis. Have a look around and take CoffeeCup's software for a free trial run before you buy. They make great software and offer the best support of any company I've ever dealt with. If you have any questions most of their software has pretty good help files and if you can't find what your looking for there come to the website and search their support articles. If you really get stuck post your request here on the forum. Don't forget to search the forum for the same question. Again welcome aboard.

Does the website and menus, prepared by the trial version works properly without any problem?

The trial versions of all the programmes have no other limitation than the time. So it should all work well.
