Thread:Talk:Extension default namespaces/Social tools' namespaces/reply

I did the revert. I read your subsequent response on my talk page. Thanks for agreeing to discuss the issue. Please note that the reservation of range 500-599 was open to discussion for 11 months (see preceding section). There were no objections, so we decided to act. The range is now reserved. Manual:Using custom namespaces was altered accordingly. Without a general, prior agreement to withdraw the reservation, I feel it should remain in force. Otherwise, what is the purpose of a registration system?
