Wouldnt that bit abit of a grey area? I mean, what if a person sees, for example the art you had made, and choose to talk and show their work, which they can be proud of too, to you to the point where both of you is in a conversation about how you two made said art
If they want to ask questions about my art, they're more than welcome to. that doesnt require them to post their own art.
If they want to ask me questions about their art, they can create a thread and ask me about it there. They can either use the @ function to notify people that they have a question for them or want their input on a post. Or assuming they've got PM capabilities on the forum, they could PM me and ask me to review their thread.
They don't need to bomb the another artists thread with their work.
This isn't just about art though, its a general thing when a thread is focused on what the OP has made. Some threads are open discussions, others are very narrowly focused on a certain thing. That's the whole point of a forum, anyone can create a thread to discuss or share something.
If someone was writing an in depth story... it'd be rude to jump into that persons thread and start posting your own story. Or to in the middle of a persons long thread that's a continual story... to post several thousand words of your own story and ask for their input on what you did.
It's the same principle.
I'm not against discussion and dialog, but it needs to be done in the right place. You don't walk into a church of one faith and start trying to promote another faith. You wouldn't walk into Walmart and set up a table and try to start selling your stuff. You wouldnt go to someone's dissertation at university's Chemisty department and ask for input on your dissertation.
Those are all just random analogies off the top of my head, so they're not perfect. My point is that a persons thread for their art, stories, etc. Is just that, their thread about their work.
It's the forum equivalent of leaving comments in other peoples Youtube videos about all the videos you've made. It's poor form and understood to be bad behavior.
