It should still work!
I only go back and make changes to LED if something breaks with a major Lemmy update, but Lemmy hasn't had a major update since January. Lemmy v0.19.4 isn't released yet, but when it is, I'll make sure the deployment is up to date.
Note that it does not have any advanced features that a major instance might want, such as storing images on S3, exporting data, or image moderation. If you intend for your instance to grow for 100+ users, this isn't for you. This is only intended for beginners who are overwhelmed by the other Lemmy hosting options, and want an easy way to host a small single-user or small-user instance.
Had to quadruple take this wasn't a Battle Network community, what a crazy thing to see on Lemmy.
We should bring back r/OkBuddyNetwork on Lemmy.
