Ok, so you now have the option to ignore people.
Yes, I realize it appears you can Ignore yourself but not to worry it won't let you.
When you click on the Ignore button you will get two links, one to return and the other to go to an Ignore page.
Here is a link to the page.
http://www.thescienceforum.com/ignore.php
You can click on ignore next to a user, or add the user from the ignore page. To delete a user from the ignore list simply click on delete next to their name on the Ignore page.
Any questions or bugs please post them here.
