On rereading my post, it did sound a bit ungrateful. Wasn't meant that way..."that ain't happening" was a reference to a long-ago explanation by Robert about the immense difficulty of implementing such a function, not a complaint.
I have nothing but the greatest appreciation for the work that has been done on this board, and features like clipboard message preservation, HTML preview, and other things that weren't here when I started have been gratefully noted.
