Tonight (Thursday, November 27) I noticed most lounges are missing.
The only one I see listed is the Geeks' Lounge. However, at the top of the page, I still saw a reference to the other lounges:
"Our Geeks' Lounge forum is the place to chat about anything. Have fun and relax in this forum.
If you'd like to hang out with other community members within your industry to discuss more relevant (non-support) topics,
you can participate in the Software Developers' Lounge, Web Developers' Lounge,
Internet Marketers' Lounge, Techies' Lounge, or IT Professionals' Lounge."
However, if I click on the "Software Developers' Lounge" link, the following message pops up:
"Invalid Forum specified. If you followed a valid link, please notify the administrator."
(I didn't check out the other links.)
