Some of the OR related articles on Wikipedia are inaccurate (see this for example) and Wikipedia does not have articles on interesting OR topics (for example there is no article on the ordering policies or join replenishment ideas)

OR articles on Wikipedia obviously need some attention.

My question is how can we join forces to improve these articles?

I have made a project page on Wikipedia there is a "To do list" on that page in which you can insert the articles that need attention and request new articles. If you would like to help in edits you can also add your user name to the list of contributors and we will ask for your inputs as we work on articles.

Even if you do not like to edit Wikipedia articles please consider helping with populating the to do list and I will try to work on those articles as much as possible

What other methods can we use in order to improve Wikipedia in our field?

Update: The project now has its own user box. If you want to show your passion about Operations Research you can place this tag {{User OR}} on your Wikipedia profile page
