It probably wouldn't hurt if Skype put a dollar converter on their website somewhere. It can be just a simple code, you type in the dollar amount and the euro or whatever amount shows. I'm sure Skype can do this, but if they want the code, I'll be glad to get one for them.
Best currency converter www.xe.com
Problem is that this isn't going to be exactly what your credit card or bank gives you...there rate is usually slightly worse than what www.xe.com displays ...so for a trully accurate rate you will have to visit their websites and use their own currency converters (if they provide them)
