(I prefer keyword oriented commands instead of letter oriented commands.) On the other hand, for most mail systems I know of, once you've posted a message, that's it, and users will always be asking to 'unpost' a message after they've gone past the point of no return. And in general, that applies to most systems.. from manipulating files to driving automobiles. There's a point of no return that you cann't back off from, and users just have to be careful at those points. --- Richard Arpa/Internet: Richard_Conto@um.cc.umich.edu Usnail: Richard Conto Ma Bell: (313) 764-9423 Computing Center 1075 Beal ave.
