@missydelinquent,

This sounds entirely new to me. This using the Firefox plugin? What version of Firefox are you using? And your OS -- Windows?

@marksaka,

Can you share your browser and let me know how you're adding them to your account (vocab page button, clicking on popups, using the Firefox plugin?) This sounds like an encoding issue, which is strange since if your browser supports the site it should be able to send the data correctly.

Please share this data and I'll try to replicate the problem.
