To be fair, this is an Alfred related site. The file attachment module does say "…file types gif, jpeg, jpe, jpg, png " which is obvious, I get it.
My point being is, the .com implies that the workflows shared here and on personal websites are (to some degree) mutually exclusive. The lack of help text, hints, text, or a FAQ that clearly states that alfredforum does not host actual workflows is surprising. It may appear obvious to you, as a user who clearly has been around these parts for a while, but for new users who aren't familiar with the forums, sending them on a wild goose chase sucks. Once more, the "Go to the Workflow Help & Questions forum for questions" link points right back to same page.
See how the verbiage could be confusing? In addition to this, in most places where a user would expect to be able to attach/upload/include a workflow, there is zero indication that AlfredForum doesn't offer that feature.
Helpful Suggestions
The file attach error could be more useful, ya know, incase a user missed the help text… Easy win…
Considering Workflows are "Other media"… heres an easy win…
or this one… it looks different from the other Inserts now… Much clear! Easy win…
I wanted to attach a Workflow to my posts, which isn't exactly how that works… What if there was some text to support the user behavior Alfred Forums prefers? Here is an easy win…
Well if this isn't idiot proof… I don't know what is…
Oh, this is one I really like… Seeing how this is the "Share Workflows" forum… A user might assume they can included them in the post, optionally of course…

Literally a slight bit of attitude and you get a bunch of free UX work. Must have been feeling generous. Your lucky day I guess!
