The discussion revolves around the inability to post email addresses, resulting in an Error 500. gerhard initially suspects it’s related to PR 4138, but sam identifies it as a regression in extract links, causing a NoMethodError. zogstrip investigates and eventually confirms gerhard’s suspicion, fixing the issue with a commit.
It’s not possible to post an email address anymore. The following produces an Error 500:
[foo@example.com](http://foo@example.com)[email]bar@example.com[/email]This seems to be related to PR 4138.
parsed.path seems to be nil for email addresses. Does it even make sense to parse URIs with a scheme other than http and https?
Nahh not that, its a regression in extract links

I think @eviltrout fixed some bugs there recently … not sure.
Actually, I might have introduced that bug. Having a look.
@gerhard was right after all
