Well, all this information can be found here http://support.skype.com/?_a=knowledgebase and here http://www.skype.com/intl/en/help/guides/ So I don't see any point in translating this FAQ But that's ok you've done it, it can be like an advertisement. Thanks.
BTW, I've noticed some mistakes:
Where did you see that? Great Britain is used without any articles. (but "the United Kingdom")
The USA
It's the First Conditional:real possibility - if +Pr.Simple ... then +will+base verb.

Anyway, +5
