I'm not sure I understand. Actually, I'm pretty sure I don't understand :-D
You can create a short URL from a long one with https ://bitly dot com, http ://goo dot gl, http ://tiny dot cc, probably others.
If you want to shorten the displayed text, that surely depends on what is doing the displaying. I'd expect Facebook and the like to provide a facility similar to DPR's. Otherwise, you need to edit the html somehow, which looks like: < a href="Link">text< /a>
So you change
< a href="
http://www.dpreview.com/forums/post/53461074">This is a question that I really don't understand< /a>
to
< a href="
http://www.dpreview.com/forums/post/53461074">Stumped!< /a>
Note the above has spaces before the ":" and after the "<" to stop this forums cleverness and just display the text. The forums don't seem to like shortened URLs either.
