To answer a few of your questions .... In my example, I gave a total of all amounts pledged. This of course does not make sense and I'm now not even sure why I wrote it (it was the last thing I wrote before going to lala land). I have no intention of doing that. What I will do is, give totals for each currency used (which is what I wanted to get over in my first mail). As I said before, nothing complicated is happening with this. It's just a simple pledge and people will make the actual payment on another site. There could be a lengthy time lapse between when the pledge was made and when payment was made. It's just a guide. That's all. Hence, actual exchange rates are not needed. So I guess my question is; is it worth using the Money gem or is it better to store a few major currencies in a table, give the user the selection and then just add a simple general formatting rule. I prefer the second option but I'm open to change my mind. I will check out http://www.bloomberg.com/markets/currencies thank you Phoenix Rising.
