I had suggested many questions and answers an edit and my edits were genuine, those posts had formatting or grammar mistakes but many of my suggested edits got rejected. Since many posts had only one mistake (or more but less than 6) and according to AU editing rules there should be edits at 6 places or more otherwise it doesn't allow to save the edits for a low rep user like me. Thus, I edit their question a little bit more (like replacing ubuntu with Ubuntu and apt-get with sudo apt-get) so as to make edited characters more than 6 but then my edits are being rejected. On the other hand some user with high rep doesn't have this limit (editing post at 6 or more places), thus there edits are directly visible. So how to edit such posts for a low rep user like me and if i edit them correct way , why are they being rejected?
