I have questions

If you go to your profile there should be a button for Edit Profile and from there a button to add a profile picture
It’s not required, but it’s nice to set yourself apart with it
You can make friends or just hang out or make random posts, or some things I won’t encourage(sexual posts mostly)
Whatever you want to do honestly
There’s only a few rules, mainly don’t call anyone out by name on posts in a negative way, no nudity that focuses on the genitals or showing intercourse(or anything pornographic really), no harassing people(including making a second account to talk to a banned person or just going to other posts to continue a fight with them, etc), don’t change your age to talk to minors, obviously don’t talk about things like rape or pedophile, and try your best to mark everything as appropriate to respect everyone’s filters(such as marking a mature post as “Adult”)

Boy this turned into a long rambling response, hope it helps
I just kept righting😅

Tap on instructions buddy.. it will not blast.. do it
