I) Easier to know how many or how few characters are left
- Player will know when to stop adding stuff to their signature
- Player will know that they can replace bits
- Better than repeatedly previewing or (attempting to) submit the signature to see if the character limit has been reached (especially for those with slower connections)
CONS:
I) Probably a lot of work for the Techies
II) Some people may find it pointless
- Suggestion near-trivial for those with faster conections
Feel free to point anything out that I have missed!
