msluyter: sorry to hear about the signup troubles but the motivation length is min 140 chars. We don't think that this is too long (one tweet?). Adding a more line or few more words should do the trick (e.g. write something about yourself or if you prefer a poem!). At least we don't use re-captcha - each time I sign up for a site using that I need at least 4 or 5 attempts ! Thanks to this HN submission we are received a lot of applications so you can make it too! (if you want of course).
