hi john!
thanks for ypur answer! =)
i know that if i remove start and end date of registration, the guest users not expirese, i dont want remove this field, but i want change the method with this information are insert in form.
i want use a check box with number of hours that the guest account have for connect.
for example two four or twentyfour hours, because the calendar that is now in used on the guest provisioning page, is in english format, i'm italian and i prefer use of 24 hours and not 12 hours.
so if not possbile use a check box, i am happy too if i can use the italian format of date.
for the username of guests, there isn't any solution?
thanks!
