Rather than waiting I'll share what I know and am aware of. JS can add to it later or if he gets a chance to.  There has been a shift in how tests this season are provided and promoted this year by HQ. Where in previous years mods (meaning Rob) would be on the hunt and provide tests for the community. This is no longer the case and all testing opportunities come directly from HQ. We as a mod team have been assigned to run and manage them, but asked to leave the sourcing of them to HQ.
