Here's how to put another forum member on "ignore." Hopefully I'm providing the correct steps:
1. When you are logged in, you'll see a blue bar on the top of the page with different options to click on. Highlight, with your mouse, the option that says "Profile"
2. When highlighting the "Profile" option, you'll see a choice that says "Account settings". Click on that.
3. That page will then offer a "modify Profile" option; highlight that, then highlight the bottom option that says "Buddies/Ignore list"
4. Click on the option that says "Edit Ignore list."
5. Fill in the box that says "member" with the username of the member you want to ignore. Then click "add," and it's done!
