Re: Drummerworld forums on the iPad are rendered very badly
It renders like this on all browsers. The only difference is that some load the page zoomed in on the main body, and some don't. I agree that it's crazy that the pages don't condense in forum view like they do in thread view, but I would assume there's some kind of limitation in vBulletin that makes it that way.
Unless iOS doesn't have this feature, you should be able to just double-tap on the main column of threads and have the browser resize to accomodate only that. Chrome for Android has this functionality. Otherwise, just zoom manually.
