We have updated our Currency Conversions feature so that it now downloads a list of conversions nightly for a majority of our currencies. Each night the rates will be updated on the site so you won't have to manually update the rates as they change. You can however manually update the rates if you'd like to input newer rates than what is currently available.
This should help keep your accounts better up to date and take the responsibility of keeping the rates updated out of your hands.
The currency conversions are provided for free by Time Genie
