Wikipedia:Edit lock

Wikipedia does not use pre-emptive software article locks on pages, because this would be contrary to the policies of Wikipedia and spirit of openness. Page protection is never to be used for closing down an article's normal development and community editing, and should be used only to prevent actual disruption.

in use template
On the other hand, we do have in use tags, which can be used to alert people that you are in the process of making a larger edit. The article remains open to editing, but courteous users should leave it alone until you're done. The template looks like this:

intranslation template
Also,. It's the same as, but it's used when an article is in the process of being translated from another Wikipedia into the English one. Again, it should only be used while you are improving the article.

It also adds Category:Articles in translation as a category in the article, which of course gets removed once the notice is removed, too.

archiving template
If a talk page is actively being archived, add archiving to the top so the archival doesn't clobber edits.
