Among Wikipedia's options is the creation of a groups who wish to collaborate toward creating or improving particular topics or categories. "One such is the Texan Collaboration of the Month."
The self-description is "Every month, a Texan Collaboration of the Month will be picked using this page. This is a specific topic which either has no article or a basic stub page that is directly related to Texas, the aim being to have a featured-standard article by the end of the period, from widespread cooperative editing."
This month's collaborative effort is described as:
"The current Texan Collaboration of the Month is Marshall, Texas. Every month, a different Texas-related topic, stub or non-existent article is picked. Please read the nomination text and improve the article any way you can."
