hmmm. I think I'm still too much of a wiki newbie to understand what this 'markup
in the sidebar' means.
I can tell you that I've put $wgExternalLinkTarget = '_blank' in my
LocalSettings.php, and I've tried using the following on my MediaWiki:Sidebar page:
**
http://mydomain.com/gallery/ | Photo gallery
and
** [
http://mydomain.com/gallery/ Photo gallery]
In the first case, the 'Photo Gallery' does not open in a new page, and in the
second case it doesn't even show up as a link in the sidebar. I think I'm
confused.
Thanks all!
