Instructions for using Stylish to not display posts of ignored users (make sure you install the Stylish addon if you want to do this):
There's very minor differences between the two, but nothing significant. For Chrome:
Click on the Stylish icon (top right hand corner at least for me), and click "managed installed styles".
On the left hand side of the screen, click on "Write New Style"
Beside "Applies to", click "select", choose "urls on the domain", type in "www.bluejaysmessageboard.com", and click "add".
Under the code section, type in ".postbitignored {display:none !important;}" (without the quotes, make sure you don't miss the "." before postbitignored).
On the left hand side, type in a name for the style (I chose "bluejaysmessageboard"), select the option for "Enabled", and click "save".
To toggle it on and off, just click on the Stylish button and choose enable/disable.
For Firefox, the icon is likely in the bottom left corner:
Click on the Stylish icon, and click "Write New Style", and select "For www.bluejaysmessageboard.com".
Enter a name for the style (I chose "bluejaysmessageboard").
Between the curly braces following the section that says @-moz-document domain("www.bluejaysmessageboard.com"), add in ".postbitignored {display:none !important;}" (without the quotes, make sure you don't miss the "." before postbitignored). Click "save".
To toggle it on and off, just click the Stylish button and click on the style name.
