QuadratureSurfer

I don't think the official Reddit app has ever supported this, unless it's a new feature?

Only 3rd party apps supported this, but a lot of those have been killed off. You might still be able to access this feature through old.Reddit:

I'm not sure if you meant "multi-communities".

In the fediverse, PieFed is a useful one where you can combine different communities into "feeds".

For instance, there are a bunch of different "technology" communities, but all of their posts are combined into this feed: https://piefed.social/f/tech

In android, if you go to the website, then click on the 3 dots -> Add to Homescreen -> Install
Then you'll be able to use PieFed and browse communities in the way (i think) you're asking.

Otherwise this is also possible with the Android app "Eternity" which let's you create your own "Multicommunity". The advantage to the PieFed one is that someone else has already scoured the fediverse for you and combined them.

This is awesome! I hope more groups start doing this.
Edit: Are they using a script/tool for this, or are they manually copying over the questions and answers?

Hmm a very interesting point. And I don't think we want to implement a "blue check" symbol for verified accounts.

True, but the coolest thing is it just goes to show another benefit of the fediverse. We're still able to post/comment on here with alts even when their servers are having issues.
