The security/performance evaluation of the old http://content.open-ra.org/ turned out to be problematic. That is the only reason why we did not want to expose it to a greater public. For the next release we will definitely use and promote the rewrite.

I already redirect people there since OpenRA/OpenRA-Resources#141 as it is the only convenient way to import legacy map at the moment.

#113 now mentions it on the front page.

Featured it in #127.
