Sounds good, but please be carefull!
&action=
&lang=
seems to be reserved words in HTML-land...

Don't try to use these in an URL, because some browser versions/email 
programs cut off the rest of the url (after action or lang).

We have had troubles with this about a year ago...

We sended out a mailing using webmacro, with a link to unsubscribe from the 
database.
e.g.
http://www.traction-it.nl/prg/wmmail?firm=MyTest&lang=NL&action=unsubscribe

What hapened was the following:

We got back a lot of error messages in the log files, after examining the 
hits we saw the error's came from the following links:
http://www.traction-it.nl/prg/wmmail?firm=MyTest&lang=
http://www.traction-it.nl/prg/wmmail?firm=MyTest&lang=NL&action=
A lot of client browsers/email programs didn't send the rest of the url...

It could be that this problems don't occur anymore, but I thought I could 
better trow it in the group before WM WebApp is up and running.
