I've been trying to compile an overview of what the various WikiProjects on the Swedish and Norwegian Wikipedias (sv,no,nn) have accomplished. The reason is that some of the best work is done within WikiProjects, and I want to find success factors and bring inspiration for other projects to improve.

Most projects have a list of participants and some way to indicate which articles they try to cover. However, the people who do actual work within a project are not necessearily the same who have listed themselves as participants. And an edit in an article isn't necessarily "part of" the project. For example, if I edit [[Napoleon]] to describe a disease he had, that edit is possibly part of WikiProject Medicine, but not part of WikiProject War.

To better assess the amount of activity within each project, it would really help if each edit could be tagged as belonging to a WikiProject. This is how I think it could work: In order not to make things complicated for beginners, the default behaviour will be just as it is today. But in the personal settings, I should be able to specify a list of tags for tasks, projects or teams that I'm involved in. The elements of this list would then appear as a <select><option> drop-down in the edit page. If a tag is selected, it is saved in the revision history and can perhaps be seen in RecentChanges and article history. Recent Changes and user contributions could use these tags as selectors, so you could get a recent changes per WikiProject.

This is just a suggestion. I'm not about to implement this. If you think this is a good idea, feel free to use it.

What I propose is just a single, free form plain text tag to be associated with each edit. I don't suggest that the system must verify that such a WikiProject exists. The scheme is not limited to WikiProjects. But there is where I see its first use.

Here are two examples of team statistics on other websites, that might serve as further inspiration:

On PGDP.net (Project Gutenberg's Distributed Proofreaders) volunteers proofread pages from scanned books. It's also a competition to get a high page count. But members can join teams and teams compete on the sum of their members' page counts.

On LibraryThing.com, members are able to catalog their personal libraries and bookshelves. They can also join discussion groups, and each group has a list of which members have the most books. A sum of counts is also presented for each group.
