yes there is =)

imagin, u open the edit form, content is the actual page...
ur working on a change...
someone else is doing the same at the same time, the one who
saves the pages at last will "win", the original  page + his changes 
will be saved, the other ones will be lost.

so id like a warning that someone else allready working on the page
or even better "locking it" ;)
