How to "hide" a member's posts?

I've never found it necessary to "hide" someone's posts here. Until now. I'm sure it's simple, but I looked at the user's profile and my own and can't find it. Where is that option hiding? Thanks.

Click on the QuickJump Menu and then click on user profile at the bottom... then click on the section marked "friends and foes".

Or you can click on the members profile, select the contact tab then over on the far right you can select add to friend's list or add to foes list.

Done! Thank you both.
