One thing that annoyed me about moving to Lemmy was that I’d lose my subreddits and that looking for and joining communities on Lemmy would be tedious. So (logically) I spent 2 days writing a script, that gets a list of your subreddits from your reddit account and looks for communities with the same name on Lemmy. It also joins those communites. So all you have to do is download, enter your credentials and you’re done.
Because some of these communities are more official than others. For example, I modded /r/simpleliving and made !simpleliving@lemmy.ml, but !simpleliving@lemmy.world also exists. It would be a bit annoying if users were directed to the less-active and less-official community over the one I made just because it happens to be on lemmy.world.
That’s a fair point. In this case your lemmy.ml community would also be subscribed to, if it’s any consolation.
