Google+ Community moderators can now enable or disable the “Ask to join” setting

A small update to Communities today allows community moderators to enable or disable the "Ask to join" setting; a feature which has been highly requested.

Previously, when a community had been created, you wouldn't be able to change who can join the community, an option presented during the initial creation. With today's update, community moderators can toggle the setting when editing their community.
You'll find the new option when editing a community
For example, when creating our public Google+ Updates community, we let anyone join the community and take part. If we wanted to restrict people from joining freely, we can now toggle the new setting so people would need ask if they can join the community, and we'd have the ability to grant or deny. Google+ Updates community members need not worry, we have no plans of restricting membership anytime soon. :)

As part of today's update, private communities can now change between “hide it from searches” and “people can find it and ask to join”.

+Brian Glick announced the update just moments ago, but should have already rolled out to community owners and moderators.

Hopefully this update is foreshadowing an update to where communities can be changed from "public" to "private" and vice versa, so that Google+ community owners don't have to create a new community if they mistakenly made their community the wrong level of privacy.

With this new update, will you be changing the settings of any of your Google+ communities?
