I have been looking for a plugin that did something like Subscribe2 from Skippy (skippy.net) but with this difference: it automatically excludes a new category unless I change it in the admin area of Subscribe2.
I am using this for a newsletter (which is a category) but I also use tags so I generate a lot of categories...
I modified the subscribe2.php file till it did what I want it to do:
- every added category / tag is automatically excluded
If you are interested in this modified file - let me know.
