3 important things to know about wiki style:
-I think it's a good idea to have all the articles in the same tone, it allows for common understanding and gets the same point across.
-I think having the currency conversion on a wiki page id good as well. It helps out travelers, but at the same time it could get crowded since there are many different currencies.
-Finally it says "don't tout" meaning don't push the issue or topic. The writer is supposed to remain nuetral and pushing an opinion would be against the rules.
