It depends on the amount of work that goes into it. Minor edits aren't allowed, but making a 100% new sprite or a complete sprite replacement including all of it editing is.
Good to know.
How do you open a news topic without the possibility for others to be able to post, since this is what news is all about - news - not posting and hijacking the thread, like it is the usual practice.
The dumb ability to post and comment was invented with the digital era and thus gave birth to trolling and spamming or just plain stupidity like Aol talk, such as the famous LoL. Global liking and disliking and even liking and disliking comments - which is absurd.
I remember The famous Legend of Link hack for Nes on some other forums - the News topic was flodded with flame-spamming between repro cart lovers and repro cart haters, when in fact only small amount of posts were on the game in question. Since as you know this game got carted.
So yea, I would give it a serious thought about how to be able to make a News topic simply to inform people of something without the possibility for anyone to post/comment/like/dislike - what the actual news is all about; since it seems a lot of News topics just get spammed or get derailed or go completely off topic - or in fact become a playgroung for (very) bad critics.
