Forum:Why do some wikis have more features?

I am an Admin of http://nonciclopedia.wikia.com/wiki/Pagina_principale, an italian wiki, and I noticed that other wikis have some features we don't. For example, wookiepedia has an image in the search engine, which we cannot enable. I asked them and they told me it was a special extension for their wiki. Could it be possible for us to obtain that extension? One other question: since we've been having problems with vandals, is it possible to enable editing for registered users only? --Mr.Bean 16:19, 11 February 2007 (UTC)


 * You can upload an image to the search box if you call it Search_logo.png, for example: w:c:starwars:Image:Search logo.png. You cannot restrict editing to registered users, it is against Wikia policy. --Splarka (talk) 21:43, 11 February 2007 (UTC)
 * thank you very much for the advice. I had seen the english uncyclopedia restricting the editing, but they are not under Wikia, so I was misled. cheers --Mr.Bean 20:25, 12 February 2007 (UTC)


 * The english Uncyclopedia has no restriction on anonymous users editing or creating pages (unless the page is semi-protected). furry.wikia.com has had to restrict editing by anon IPs temporarily during raids. The only general wiki hosted on Wikia that restricts anon editing completely is Wikiality (not counting university wikis that restrict editing by anyone but approved users, starter/notreal/wikia-inc.com that restrict editing only to staff/sysops, and kennisnet). --Splarka (talk) 23:21, 12 February 2007 (UTC)
