These are the vocab lists that words will be added from during practice. To select different lists, go to the vocabulary page.
You don't have enough words selected to study (you need at least 4). In order to get started practicing with Skritter, please go to the Vocabulary Lists page to choose what you'd like to study. (Or make sure you're studying the right language--you're in Chinese mode.)
Skritter is running slowly. If possible, please close other tabs and programs that might be using many resources, like Gmail or Outlook.
If that doesn't help, you might want to consider upgrading to Google Chrome, Google Chrome Frame, or Firefox. Chrome usually runs Skritter significantly faster than other browsers.
This is an experimental warning, so if it's popping up inappropriately, please let us know. We're always looking to make Skritter faster, so if it's running slowly for no reason, tell us about it so that we can improve. Click this popup to close it.
