[thelist] add to favourites and bookmark this page

[Bird]

I need to have a text link that adds the page to peoples favourites
folder.
That bit i can do with this code:

<a href="javascript:addbookmark()">Add to favourites</a>

I know that this is IE specific but don't want people using Netscape and
Opera to think that the link does not work.

What code can i add to remind people using Netscape to use the add
bookmark feature in their browser?

Thanks

Lisa
