I don't know if I did something wrong when I set up the external data provider, link but they never showed up in the CMS for me, only on the forum threads.
I finally found this link
https://vborg.vbsupport.ru/showpost....95&postcount=8 and TADA!! I now have all the links I could ever want on my CMS. I even put the same code on the threads in forum (scroll up to the start of that link to see where & how) to get the same options on the forum. If vBulletin won't give me site-wide continuity I'll do it myself!!
edited to add the external data isn't the one you want:
admincp>settings>options>Thread Display Options (showthread)>Enable Social Bookmarking>click 'yes' and save
Then select the ones you want to have listed:
admincp>Social Bookmarking Manager>
You can Toggle Active Status for All, or select each one you want to be active. You add new bookmarks using button at the bottom of the box. There are a couple of links that I found very helpful finding links and icons:
http://www.vbulletin.com/forum/showt...kmarking-Sites and
https://vborg.vbsupport.ru/showthread.php?t=166332 .
Hope that helps!
