Since that locking old threads decision we have also added a notice that shows the time elapsed since the last post to indicate more clearly when a thread has been resurrected.

Sometimes it's useful to be able to add information to old threads, and sometimes it would be better to just start a new thread. If you want to you can still link to the locked thread.

There's no solution that will solve everything and make everyone happy. It is what it is. If there is a thread you find that you want unlocked, message a moderator.

Anyway, none of this conversation has anything to do with S curve acceleration.
