I shouldn't be laughing, but I am.
Not sure if this is a glitch or something intentional (teehee) but the background for the FFXIV forum front page is a massive Rift ad. As I recall, Blizzard had something similar around Cataclysm launch and if it's some paid ad revenue for ZAM I say more power to you, but those crazy cats over in XIV land are gonna scream.
If it's NOT intentional, here's what I did:
1) Was browsing Rift general forums.
2) Navigated to FFXIV site through the Network drop down in the upper right corner of screen.
3) BAM! Rift ad behind the XIV panes.
4) Navigated to FFXIV General forums. Rift ad gone.
5) Navigated from FFXIV General forums back to front page from the Network drop down menu. BAM! Rift ad.
I can already hear them sputtering with indignation...
