Hi to the DW tech staff.
I was thinking about the Location field in the public profile page for members as we have discussed it recently in this forum since it has been removed from the title bar for posts. Anyway I was thinking that it would also be handy to know if English is a member's first language. A field such as First Language and possibly one for additional languages spoken might be useful for those who take issue with people struggling to describe the problems they are having.
I have found the Location of a person handy for working out why people have spelling or grammar mistakes in their posts, but sometimes it can be misleading. Just because someone is from Chicago doesn't mean that English is necessarily their preferred language.
Anyways, just a suggestion.
