Question

What happened to the Beta topics?

Answer 1

They graduated!

Explanation:

The last beta subjects that were active on the site, i.e. US History, World History, Psychology, Environmental Science, and Astrophysics, have graduated to full-subject status.

All the contributors that helped push these subjects out of beta received level badges -- I see that you have one in US History, way to go! :)

I'd like to take advantage of this opportunity to say THANK YOU to everybody who helped these beta subjects graduate!

The road has been long and arduous in some cases, but the results speak for themselves.

I'll let my good friend George sign this off! :D
