@waftingluna hello 
This is an excellent first post :)
You're doing great and we're happy you're here.
Even if you lurk 99.9% of the time, that's okay
But if you want to reply whenever you're comfortable everyone here would gladly welcome you to the conversations (most of them are pure silliness anyway haha)
And if you want to start slowly, boosting posts you like helps spread good content around (favorites are just an "I like this" note for the author). Reactions are great too
