How can a thread be closed?

[Chrystal162]

Someone just closed a thread of mine that I would have closed myself, had I known how.

The same person that closed my thread closed someone else's earlier. Can anyone do this? Please advise on how this can be done.

Thanks!

Only a mod can close a thread.
