Will be great to develop these features in NHS:
1. In list of anchor texts for link will be good to confgure two or more types of encoding. Every type will be executed if encoding of current page is... "some encoding". Example: i want to configure different keywords for blogs that are with latin encoding and different keywords for blogs that are with utf-8 encoding. In this way anchor texts of comments will be on cyrillic on blogs that are with utf-8 encoding and others will be posted on english (on blogs that are not with utf-8 encoding). To work this function, your program must know encoding of current page.
2. You say that your program now check posts to detect auto approved comments - "check posts for links" option. Will be great to save in database also type: follow or nofollow are these links and is good idea that both types can be exported separately.
If these features are not possible to develop in your software, please, post here guide how to do this with other software, these things are important.
