As others have mentioned, this happens when you're using AdBlock I understand the use for AdBlock and I use it on many sites with inappropriate/intrusive ads, but I hope you'll consider disabling it to help support the site! If you come across an ad that's inappropriate you can screenshot it and send it to me, I'll report it to Google so that it doesn't show anymore. Thanks!
I'm not sure if you meant multiple editors on a post here on the forum? If so, that's not going to happen, sorry. Users can't edit each other's posts. But if you meant mod posts on the main site, that's more what I was talking about, and let's just track the progress in this thread instead: https://forums.gta5-mods.com/topic/614/author-and-helping-authors
@player2 It most certainly would be interesting. A concept like the "Follow new updates" button on a person's page. For example, if I follow Lundy, I would click the button and it would give me a notification whenever Lundy posted a new file. If I follow the Vehicles section, I would do something, and it would give me a new notification whenever something is posted.
