Ok I now know how to unlock old threads that were too old to edit and as you'll see in the other sections I've worked out how to stick threads to the top of the section, and I can unstick them as well, so let me know if you want a topic stuck, even if you only want it stuck temporarily, for example an event etc.

I won't stick everything or it will become too crowded at the top, but I'm happy to stick those build threads where you've asked people to not reply.
