Hi, my name's Michael.
I just signed up and tried to make a post to critique my pixel art attempt, but I can't find a way to upload the PNG file.
I looked at the 'Help' section and the closest I got was reading this:
Attachments - If enabled, this feature allows users to attach files to their posts in the same way as most e-mail clients. Users simply have to browse to the relevant files on their computer before selecting Post. Multiple attachments, up to the limit set by the administrator, can be added to a single post by selecting the Additional Attachments link. Users can delete their attachments or add more by modifying their posts. The permitted file types and sizes are set by the forum administrator. Some forums may display image attachments in line with the post or show them as thumbnails below the post.
Do I have to wait 24 hours until I can post an image or something? I have no idea.
