iTuN3r / Peggy :
It is clear you are "Super" interested in mobile browsing.
You therefore must already know this information:
(1) what percentage of hits on your site is from a mobile device ?
(2) How long do mobile users stay on your site ?
(3) what percentage of your core users access the forums a majority of the TIME on a mobile device ?
(4) what percent of google ad revenue is from mobile devices ?
Edit: There is VERY Little discussion about Mobile Browsing and Xenforo ... there is a Mobile Style ....
XFStop Mobile Style
Isn't that pretty helpful ?
