Fantastic.Since I use WP with buddypress as well as bbPress,teachPress, and Vanilla/Garden I had a heck of a time for my site to load in any version of IE.
I tested my site with this plugin using the "plugin test drive" plugin using 4 themes that accept all of my tweaks in my default browser and this T2B plugin works like a charm.I have now activated T2B and my site shows finally on IE8, Google Chrome, Firefox right up to version 4.0 ,and Safari.
I do not own a Blackberry nor I-Phone so cannot test html5 there, with the WPTouch plugin.
However I will ask some friends. I also tested on the Opera browser and the T2B plugin works perfectly.
Since my site is for members to access the special features like buddypress and teachPress and the Forums you would need to Register to see them.I have tested this great plugin in various browsers both as a guest and as 'signed-in' on my site.
Try it yourself in various browsers to see for yourself.Only IE will not load my preferred header banner and incorrectly assumes a left sidebar, but it now at least doesn't scramble nor shadow my site which is http://biggerpractice.com/
