This link module is a piece of software I use since years on different applications, and it works.
I did a very fast adaptation of it for moregroupware. So you may find the sources are complicated, yes there are !

I did not adapt a part of it, a mailing part of it. In the original, each time a link is added, it is mailed to a list. Not there.

The language are french only, and some english ...
