No worries, lots of new users nowadays. It looks like your home instance is lemmy.fmhy.ml, so you can search for relevant communities here: lemmy.fmhy.ml/search (it’s the magnifying glass in the top right).
That shows you communities that your home instance is already connected to. Out of those, I’d say [email protected] would be a good place to post this, you can subscribe to it here: lemmy.fmhy.ml/c/[email protected]
