How many signs are there?

Currently there is just over 40,000 videos listed on this site. Signed by more than 150 different signers.

Why is there sometimes multiple signs for a single word?

This can be for several reasons. Firstly a word can have more than one meaning, and thus the sign changes for each meaning. Also, there can be regional variations on how a sign is presented.
