First you verify your char by purchasing crystals for a certain price from the Jueno/AU Auction House, which is appears you've already done.

Then go to your members menu on the top right, and click edit chars. There's a field in your profile that you need to fill "LS Community Profile URL". To get the proper URL, go to:

http://fanzone.playonline.com/lscom/index.do

Sign up and create your LS Community Profile, then when you're done, view your profile and copy and paste the URL into your FFXIAH profile, under the field I mentioned earlier. For example, my URL is:

http://fanzone.playonline.com/lscom/characterAllData.do?EQUIP_LINKSHELL_ID_STRING=Qni5Gl1aLAtFP739DG4N2RAFbej6-2BDzYvhnlT9XSo1U-3D&VIEW_LINKSHELL_ID_STRING=Qni5Gl1aLAtFP739DG4N2RAFbej6-2BDzYvhnlT9XSo1U-3D

Then voila, done.
