Editors ... calling them, or PHP-based one?

Sorry for vague subject, only so many things you can put in there ... I'm looking for someone way, in PHP4, to take a "form/template" for a letter on the server side, pass it to the client, let them edit it (including markup tags like bold and underline) and then pass it back to the server ... It has to be relatively transparent to the end user ... I don't want to have to teach them to put <B></B> tags around where they want bold ... I'm not particular on editor ... right now, if I have to force the client to install StarOffice for commonality across platforms, I'll do that and expand from that ... but some way of 'click here, download doc to computer, open up file with <insert editor of choice>, save back to server (if possible)' ... Ideas? thanks ... Marc G. Fournier ICQ#7615664 IRC Nick: Scrappy Systems Administrator @ hub.org primary: scrappy@hub.org secondary: scrappy@{freebsd|postgresql}.org
