I have a form that two users need to fill together.

Each user has his own fields, but can fill in the other user's fields too.

I give both users the link to the form - but I need to mark the fields in some way, so each user will know what fields are on his responsibility (to be filled or to be checked, if the other user filled them).

How can I do this? any way to format the field's title?

Thanks
