Simultaneous editing in Zoho Wiki pages
If two persons edit the same Zoho Wiki page simultaneously, the last one who saves the page "wins", and the other one loses his work.
One solution could be, at least, that as long as this problem is not solved, the page should be locked for edition as soon as somebody is editing it.
Example:
John starts editing at 8:00, makes some modifications, is disturbed, and goes out.
Bill starts editing at 9:00, works all day long, ends and saves the page at 18:00.
John comes back at 19:00, saves his work started earlier, and erases all Bill's work!
