first, cross-posting doesn't make a topic more popular. Here in the French forum are plenty of people with the right knowledge to help him along if he gets stuck. Nobody really cares what he is, where he is, the only thing that matters just like on any social site on the internet is how he writes and how he behaves.
As to the more technical side, it would be interesting to know what he want to do with the Arduino. The Arduino a tremendous tool to work with, but just like any tool, one needs a purpose to use it. Playing around with an Arduino just for it's own sake gets old and boring very fast. Hand in hand with this goes the question what kind of resources does he have available. If he want to build robots he'll need different parts than if he want to make blinky toys which in turn needs different parts then making Midi peripherals. And the other question is from where does he start, what's his experience in electronics, programming, computers, soldering, model crafting, general education? No skill of aforementioned list is absolutely necessary, but having an idea of some can be a big help and if all a lacking, things are going to start slower.
However, to start out, these questions aren't really critical. One can start with installing the software and doing the first tutorials like Blink. These things should work more or less out of the box. Once that's done, depending on what other parts he has in his kit and what is of interest to him, further projects can be defined.
He should get an account here and if he doesn't want to ask his questions in the public forum, he's very welcome to send me a PM (private message on this site), I can find the time to help him along the first steps and to help him break down bigger projects into manageable parts. If he cares, it's important that he takes the first step to reach out.
