Hi all,
I would like to propose the approval of the Dagbani Wikipedia. The activity [1] is really good and stable, and the most used messages have all been translated [2] (this was finished today actually – there were some 40ish untranslated messages a couple of days ago, so I prodded Sadik Shahadu, one of the main contributors, to complete them, and he responded very swiftly). The community is really active not only on the Incubator, but in various other areas of Wikimedia as well – as some of you may have heard, it was selected as one of the focus languages for the Abstract Wikipedia project [3]. In addition, they also have an active Wikimedia User Group [4], which I believe is the only language-based user group for a language that's still in the Incubator.
As for external validation, I am not sure that is necessary in this case, but according to Amir, who has been helping them out with some things, it should be rather easy to obtain if any of the committee members deem it necessary.
