It's all easily done from your vBulletin AdminCP:
1. Download the product XML file from the first post in this thread and save it somewhere where you can easily find it on your home computer:
product-ozzy_extra_mod_options_ma.xml
2. Go to
AdminCP >> Plugins & Products >> Product Manager (left hand menu)
3. Scroll down to the bottom of the list of installed products and click on
[Add/Import Product] (right hand AdminCP panel)
3. On the next
Import Product screen, next to where is says, "EITHER upload the XML file from your computer", click on
Browse and browse to where you saved the XML file from Step 1. Click on the XML filename.
4. Since this is your first time installing this product, leave
Allow Overwrite set to
No.
5. At the bottom of the top box for that screen, click on the
Import button.
And that's it... product installed.
Then go to
AdminCP >> Settings >> Options and find in the right panel
OzzModz: Extra Mod Options Settings. Click on that and select the settings you want for this mod/add-on... most of them you can probably leave as the defaults.
