Has anyone experimented with using the usual "Lounge" category with trust level 2

It looks like it’s lounge_welcome.body

I was wrong. This is the correct answer

@Simon_Manning

lounge_welcome.body is the content for the welcome topic inside the Lounge category, as far as I can tell editing it has no effect. Same with lounge_welcome.title , vip_category_name and vip_category_description , I think they’re just seeds for creating the Lounge category.

There isn’t an explicit message sent to users when they reach TL3 but they are granted a badge and a notification is created for that, so badges.regular.long_description might be the closest to what you’re looking for.
