mmh, now how hard is it to click a link in an email, and then copy-paste a 10-char token and your email address to 2 fields on a webpage... hmm, okay, maybe next time we should actually create a personal URL for everybody, just add the email address and token to the link given in the voting mail (not really that difficult, since the whole thing is auto-generated from a template...) Would that be simpler approach?
