Years ago, it's very common to see forums where it's not possible to upload attachments. The only way to upload attachments in such a forum is by using a third party website like imgur and the rest. Recently, I bumped into a new forum where I couldn't upload an attachment which came as a shock to me.
How recently have you seen a forum today where you're not allowed to upload an attachment?
