>MFFA will finally have a responsive theme
YESYESYESYES.
Also, it's not just the upgrades in design and shit, the upgrade also improves the shit coding done by IPB scrubs. It usually means faster and less resource intensive website.
Yes, it's responsive. The same theme for your desktop, tablet, phones or anything.
You could probably have Alexei do it though, it's not that difficult. If you can edit the css then just use the background (http://www.w3schools.com/css/css_background.asp) property.
