My wiki is experiencing a lot of vandalism lately. I would like to implement things to reduce the amount of vandals allowed into the system. Perhaps limiting the number of edits by brand new users? Requiring a valid email address by new users? Requiring a full name? One thing I would really like to do is to limit the number of characters in a new user id to less than about 12.
Is there any easy way to do any of this, like an extension or something already in the software?
Thanks a lot!

* You can set up a throttle on editing using the built-in rate limiter (see $wgRateLimits; note that this requires memcached or APC user cache or somesuch)
* You can require that a user have a valid, confirmed email address prior to editing; see $wgEmailConfirmToEdit
* For the minimum username length limit, have a look at http://www.mediawiki.org/wiki/User:Robchurch/Minimum_Username_Length

For a 'valid' id, are there any plans to have an 'image' that the user has to enter the word. Many systems are using this method for weeding out machine generated user requests.
Thanks

It's called a "captcha", and there's an extension to do this:

I think this currently works for edits, not user creation.

Thanks for both 'captcha' name and for the link

The default is to trigger on edits which add new external links (i.e. possible spam) to pages, but it can be configured to trigger on, e.g. all anonymous edits. It can also be triggered on account creation if desired.
The default ConfirmEdit contains a weak text-based math implementation which is not a particularly foolproof captcha. There's also FancyCaptcha, which requires manual generation of captcha images using a "secret" and a word list, and is the best solution. In between those two is MathCaptcha, which uses the math renderer (texvc) to generate simple sums and render them as images...this one's better than the default, but still not as good as FancyCaptcha.

Not knowing what kind of vandalism you're experiencing, I can at least say that I have nothing but good things to say about how SpamBlacklist (http://meta.wikimedia.org/wiki/SpamBlacklist_extension) has helped stop vandalism at my wikis.
