This will be a good thing. But it should only enable by users manually. If all site has it's fixed wiki logo then it will great. I suggest all users and editor to set their language preference for this action.

It would be a good part of Mediawiki if there is some software diagrams. Because it will help us easily to realise a topic.

@Aklapper: Oh! that's great. Thank you

If we think so then there should be an external site in media-wiki for developers. Media-wiki should have a store house for some important code. So that any developers can modify them by editing or collect them from this wiki. Thank you

I would like to say that Variable function will be complex for us. But it will be good if that function is available on gadget section of a wiki. I sympathize with {{Krinkle}}. So media wiki has not to need this function. But if there a Captcha function on a wiki that will be more useful for us. Thank you

But i created this task as a feature request. Please consider it.

If this issue has taken. Then it will be great. But we should know about pywikibot . Thank you
