Owing to planned maintenance, this site will be unavailable overnight on 26 September, including the early hours of 27 September. We are doing two pieces of work:

• Refreshing the design to reflect the National Autistic Society's new brand.
• Updating the software to a new version. The main benefit to this should be improvements to the listing of messages in threads, and the flagging of new messages. We want to implement this in order to help with problems that users have reported

The site should be available again early in the working day, with its new look.

Apologies for any inconvenience while the site is unavailable.
