Yo!
I reckon you should increase the number of characters in the Additional Interests box. Currently that field seems limited to NOTMANY, whereas i feel a more appropriate number of characters would be QUITEALOT.
You only give us six options and I'm not interested in any of them -- I only ticked one because there is a red star by that field and the page wouldn't let me change something else unless i did. Some people, on the other hand, have lists of interests as long as your arm, and it would be courteous to let the express themselves in this electronic void.
