The Physics Meta promotes support for all Science sites on Stack Exchange, in this post. The same meta post is now on several other science SE Meta sites.
The Astronomy SE is one of the sites that has benefited from this (and is currently still benefiting from this, if you look at the "Sites in Beta" section of that Meta post).
Let's give back to the younger science communities, now that we here at Astronomy have graduated out of the Commitment stage, and let's help some of the other sites in Beta, as they are doing for us.
Below is the post from the Physics Meta (now on several others too).
