It's actually "blank", not black :)

If you want all external links on your wiki to do that, you can set $wgExternalLinkTarget = '_blank'; in your LocalSettings.php file. It is not possible to change this for individual links.

Hi, 

I am not sure if this is right place to post this question. It's about link target black. I insert a hyper link in the wikicode. When people click it, I want it to be popped out in another new window. Anyone knows how it could work out? Thanks!

Here is how the wikicode looks like now:
[https://website..  hyper_link]
