We've been working on these for some time, and with the recent uptick in signups, we tried to finish up the first few pages so that new users could use them.
You can find them all on fedecan.ca under Guides & Resources. For those that are not familiar, this is the website for the non-profit (Fedecan) that manages lemmy.ca.
We're planning to gather some feedback on the technical Fediverse communities first, before sharing the guides more broadly, in order to catch any issues early.
If you want to add to them, feel free to reach out, and we can help you coordinate if someone else is also working on it.
What will get you more people who will stay here is a 'view all images' button like you have in RES, instead of having to manually open each image they want to see, very useful in image heavy communities. But please never use a card or full images default setting like new reddit turned into because that looks like web cancer and I won't use a site that does that
