Actually, one note – as I look again, cropping jpgs in the upload facility seems not to work; could that be a symptom of a libjpeg issue (which in turn might prevent those jpgs from getting created in the avatar)?
We’re likewise interested in this capability. I guess at the very least, everyone has the same basic goal for the functionality — each user of WPMU would be able to define a localization and language. John, what would be the best place to look if people were interested in contributing to testing patches / tracking this development? Ultimately, is it likely some combination like Jalien is suggesting will work, with other changes in the BP/WPMU backend?
