The new revamped Second Life community platform was due to go live last week but due to the large complexity of the Community migration it’s taking longer to complete apparently. For days the blog, forums, KB, Answers etc have been offline. The wait is almost over I think!
The lab have been keeping everyone updated regularly on the Community migration on the Second Life Status page under the Community Platform Maintenance section.
Today the lab are still continuing with the community migration. Hopefully the new community platform might go live possibly this week or next week. We will have to wait and see.
