Originally rrasco had the garage mod for smf 1.1.x. When smf launched 2.0, he never updated the mod.
I created smfgarage.net on converted the mod to 2.0 but he never granted me permission to release it. I quit development and closed the forum. Now he updated it to work with 2.0.
This mod here is much simpler in which is not complete at the moment.
