Attention,
we already had two people have problem for this: they answered all the proposals, and at the end they realised they were not logged in.
So they tried to log in (it should be possible to do it after without losing your answers), but this log in is buggy and they lost their answer.
Part of the problem is that we had so many new tools and browsers in the last year that what we coded last year is not working anymore. With the new vilfredo going to come soon it is really not worth fixing, but we are going instead to require to people to log in BEFORE they start answering the questions.
This problem might hit you especially if you log in using facebook, or answer through a tablet, or log in using facebook through a tablet.

We will make sure by this evening to answer proposals you must be logged in. In the meantime, please pay attention.
Thanks,
Pietro
