If you are tired of seeing the crap posted by, for example, "Luannatrigh", you can do the following to avoid looking at his drivel.
click your username on the top bar.
Select My Settings
Select 'Ignore' Preferences
go to "Add a new user to my list" and paste in Luannatrigh
select the checkboxes Ignore: Posts Signature Messages, then Save Changes
You'll still see the message header but not the gibberish in the message body. It's much less annoying and easier to scroll past. I'm sorry for spamming this message over many sub-forums, but I want to reach as many users as possible.
