Previously, user-generated links would often open in a new window/tab. However, kcud_dab found out that there are security issues with this, so I removed it. You'll have to middle-click links if you want them to open in a new tab.

If people find this disruptive, I could add rel=noreferrer to some of the target=_blank links, but then referrer info would never be sent, which might be undesirable.
