Easy, just create the equivalent of multireddits.
Pleonasm
I've been oscillating back and forth between wefwef and Connect and think I'm likely to stick with Connect.
I love all the customization options, they really let me change the UI to the way I was used to with RiF.
One thing I'd ask for is an option for text posts to have a dummy thumbnail so that all submission entries have the title, submitter, community, comment/vote counts in the same place. At the moment posts in the list without a thumbnail look a bit disjointed.
But this community is for Connect for Lemmy? Did you post a screenshot of a different app?
Can your instance not do that as is? Just spin up a bunch of fake users and make them all vote on something?
Sure, I also have been trying to learn about how Lenmy works. I haven't yet found a comprehensive overview that details everything though.
From https://join-lemmy.org/docs/administration/federation_getting_started.html
If you search for a community first time, 20 posts are fetched initially. Only if a least one user on your instance subscribes to the remote community, will the community send updates to your instance. Updates include:
New posts, comments Votes Post, comment edits and deletions Mod actions
From: https://join-lemmy.org/docs/users/01-getting-started.html
These previous ways will only show communities that are already known to the instance. Especially if you joined a small or inactive Lemmy instance, there will be few communities to discover.
This issue/post on github has some info: https://github.com/LemmyNet/lemmy/issues/3062
I would also checkout some discussions on !fediverse@lemmy.world !selfhosted@lemmy.world https://selfhosted.forum
As far as I understand, your instance is only aware of a community on another instance if at least one user on your instance has subscribed to that community on the other instance. Perhaps that's what you're experiencing?
So if you're the only user (let's assume for ease) then, that represents all the updates (posts, comments, votes) from each community that you are subscribed to?
That seems high when you extrapolate that to 10000 users, like a larger instance might have.
There's an XKCD for that: https://xkcd.com/810/
