I used to use something like http://www.mediawiki.org/wiki/index.php?title=Special%3ARandomInCategory&category=Template_extensions - it worked in 1.24wmf14 but is gone in 1.24wmf21 (2691b4d) (same version as here on Meiawiki). On mediawiki.org it just redirect to a help page, on enwiki it redirect to Special:RandomInCategory.
Is it just gone, or is it a bug? Because it was really nice feature because you could add "&redirect=no"
You have to request index.php from the Script path (mediawiki.org/w/), not from article path (mediawiki.org/wiki/). So the correct link should be:
https://www.mediawiki.org/w/index.php?title=Special:RandomInCategory&wpcategory=Template_extensions
And on enwiki i can't reproduce a redirect to the Special page (that would be false). Please notice, too, that Wikipedias running 1.24wmf20 atm, they will be upgraded tomorrow.
ok, thanks. The w versus wiki confusion comes from my try to convert the syntax form my wiki to mediawiki.org. With version 1.24wmf14 it was possible to skip the special page and go directly to a random page with your example (and category instead of wgcategory), like Special:RandomInCategory/Template_extensions. The reason I want the ?title version is because I used it like shift-alt-x (random page) from a monobook.js script - shift-alt-x doesnt work here, but on enwiki it does).
