The documentation on Create a link to start a new topic with pre-filled information says: [image]Creating a link to start a new topic with pre-filled information This feature also supports “Start a topic by pasting a link (like Reddit) ”, provided that the body is not present, for example: https://meta.discourse.org/new-topic?title=https://www.xkcd.com/556 However, even when directly copy-pasting the listed example, a redirect appears to strip one of the slashes from the URL specified after title= , resulting in the browser instead navigating to https://meta.discourse.org/new-topic?title=https:/www.xkcd.com/556 which opens a composer window for a new topic with the pre-filled title https:/www.xkcd.com/556. The behavior and oneboxing described in Start a topic by pasting a link (like Reddit) then obviously doesn’t occur, unless you manually add another / back in to the title URL. I first saw this behavior trying things out on my hosted Discourse and figured I might have something mis-configured, but then seems like a bug since it also happens with the provided example?

IMO you are expected to encode any query unsafe query params, [image]Creating a link to start a new topic with pre-filled information you can use w3Schools’s HTML URL Encoding Reference to find what text characters are encoded as in the URL, there is even a text to URL converter in the Try It Yourself section in the page linked above in this paragraph. so https://meta.discourse.org/new-topic?title=https://www.xkcd.com/556 becomes https://meta.discourse.org/new-topic?title=https%3A%2F%2Fwww.xkcd.com%2F556 that works like Discourse Meta (open in a new tab)

I’ve added this info on the guide, thanks! :handshake:
