Hausa Wikipedia is growing

Posted by hausaonline on Wednesday, July 22, 2009

About a year ago, I warned in a blog post that Hausa Wikipedia [ http://ha.wikipedia.org/ ] could soon be closed, due to lack of activity. I don’t know whether it was because of this post or due to some other factors, but since then, Hausa wikipedia is growing fast. Have a look, and maybe you feel like contributing something yourself or editing (please, don’t vandalize!) the articles that have been written.

If you would like to contribute something, but don’t know how this works, here are some guidelines [see the blog posting for links]:
* Contributing to Wikipedia
* Policies and guidelines
* Tutorial

You could start with some topic you are familiar with or translate an article from another language.

A good point to start from could be some online news articles. Some old Hausa school books like "Ikon Allah" would be good source material, too. But make sure you do not just copy what is written there, in order to avoid copyright issues.
