[Board] OSGeo Twitter

[Tyler Mitchell]

Hi all, I've been running OSGeo's twitter account for a while now.  It's auto-linked to
news and, I think, events postings on OSGeo's website.  Time to hand it off..
I've set it up to use the info at osgeo.org account.  Frank, since you're the only one on that
account, could you confirm the email (you should have an email invite thingy) 
and then I will remove mine.

Thanks,
Tyler
