We have a report of poor usability regarding attaching files. So I'm exploring.
I am creating a new topic, and at the bottom there is an Attach Files option and a Choose File button. That looks pretty easy. I'm attaching an old photo of a button "I Met MWRon" - this is a throwback to the old Metrowerks CodeWarrior days. MWRon was the guy who moderated/trolled all the internet forums for CodeWarrior issues. He was amazing.
So that looks easy enough. Next I'll try to reply and see how to attach a file to a reply.
