The page reloads with red error messages and no prompts visible:
There were some problems with this submission. Please correct the mistakes below.
Sorry! We couldn't save this challenge signup because:
You must submit between 1 and 5 requests to sign up for this challenge. You currently have 0.
In order for the prompt to save, you have to edit the challenge settings to allow at least one type of tag. Allowing Details/Description or a URL won't cut it – it has to be a tag. You do not actually have to fill in the tag field on the prompt form.
This error does not happen if either Details/Description or URL is the only field required and allowed on the prompt form. It does happen if Title is allowed but not required.
I didn't check this on gift exchanges, but I wouldn't be at all surprised if it were a problem there, too.
The prompt should be successfully submitted.
