I'll try and improve the messaging so it's clearer but basically once it's been submitted, it's safe and you don't need to wait for it to be processed.
I would like to improve the experience for established / trusted users. That will need to be reputation based and I have some modules done but need to put everything together and have a new material design UI rollout to do first.
There's always going to be the need to have some limits though because, well, unfortunately some people don't have a personal filter - if you let them they would post endlessly and that in itself can become disruptive and off putting because other people don't get a chance.
I'm not saying it's preachy people that do it ... but ... well, yeah, it's preachy people.
