If I may a post it doesn’t appear? Some places shows I have 8 posts, but my post history only shows 4? Am I doing something wrong? Or do my posts need to be reviewed first? Or a minimum amount first ?

 

the posts exists, it's just sometimes posts get flagged for moderator approval, so they are not visible to you until a moderator approves them. I checked and saw a few of yours pending approval and have since approved.
