10) Click on Save Template Bit
11) Click on Skin Manager
12) Click on the option dropdown for IPB Default Skin and select Edit Replacement Macros
13) Click on the "Add Macro" button on the top-right.
14) In the 'Variable' textbox type in "HIDE1" (no double quotes), and in the 'Replacement' textarea type in the text/image code you'd like to appear when the user has *not* replied to the topic (eg: "[ Hidden Part, you can see after reply ]"). Then click "Add This Macro".
15) Again, click the "Add Macro" button. Type in "HIDE2" in the 'Variable' textbox and in the 'Replacement' textarea type in the code for the text/image you want to appear when the user *has* replied to the topic (eg: "Hidden Part: "). Now click "Add This Macro".
16) Redo the above for any other skins that your forum uses. <-- Important.
Thanks goes to Cøbra for the macro information
