Well, I assume pretty much everyone heard of it, and some maybe have even tried it, or bothered to read a bit about it..
I'd like to hear some opinions on it, if some of you guys have..
But the specific answer I want to get, and which has made me to start this thread, is:
Could someone please, suggest me some free web(or any other, over the internet) resource, giving currency charts, with many options(e.g. to see EUR vs USD for latest day, week, month)?
I also care of less important currencies, like JPY, RUR, NIS..
In other words, I tried to but couldn't find any website, that gives rich information about the currencies, and I thought that someone might help.
Thank you.
I know of forex.. Not like I succeeded getting any charts of the needed(described in the first post) kind there, though.. 
I use yahoo finance which has vs charts and tables of all current rates, and google finance will probably allow similar options.
Yep, thank you. Google has it.
