As movable type consultant, I've developed a couple of movable type plugins to serve specific needs not available out of the box or though the available tagging syntax.
I would like to gradually make these plugins public so that any movable type user could enjoy them!
The plugin to start with is called "Blank Target" and it allows you to get the external links (links to other websites) to open in a new window. For more details click here.
You should also know that I remain available for developing plugins for your very specific needs.
