Thank you for taking this initiative, and I hope these are of only<br>

I strongly encourage anyone with interest in a particular BSP to step<br>
forward if willing to help in this vital effort at improving the<br>
quality of RTEMS releases for that BSP. I'm a little worried that<br>
these important notes about testing and tiers are being lost in the<br>
announcement about release snapshots. For a robust RTEMS release<br>
across a wide range of the targets, we definitely need some willing<br>
stakeholders from the user community to volunteer!<br>
