As you have already noticed, Astronomy.com looks a lot different this afternoon. It's a whole new redesign for the site with fantastic new functunality. Your Forums also went through a VISUAL upgrade. Functionality, however, didn't change for the most part. We just selected a different skin to make it better fit in with the rest of the site. If you have any questions or concerns, please feel free to message me.
Also, please note that the site is still indexing and stablizing. Things that seem amiss this minute likely will correct themselves in the next hours. Please be patient with the site, and we apologize for any inconvenience.
