Right now in Wikimetrics, selecting a project is odd for someone who doesn't work with the MediaWiki databases. For example, many users won't know that commonswiki is the name to be used rather than wikimedia commons. It would be great to find a solution for this (i.e. have two drop down menus, one where you select the project, a second where you select the language).
At the very least, provide a list of all the project names so they can be somewhat easily found.
