Contributing content

Our database is user-contributed. This means that you can add hand signals to the dictionary.

Anyone can add new phrases along with the signals for them, and anyone can edit existing signals.

You can also add additional signals to existing phrases. For example, the phrase "turtle" has different signals depending on where you are in the world. If you do not see the signal used for "turtle" in your part of the world, please go to the existing page for "turtle" and click Add another signal to add it!
