I'm new to this forum, and I'm still exploring it, learning how things work here etc. But I noticed a lot of threads here tend to have really cool thumbnails next to the thread before I click on it. Are those profile pictures(avatars) or do folks make thumbnails for their thread posts?
Also, as an experiment I attempted to create a thumbnail/avatar for my profile and I got a message saying I'm not allowed to do that. I'm guessing because today is my first day in this forum that I'm aware of and just made my profile today. this is literally my second post lol.
