Members of the Class of 2009 will walk into Sanford Field House on Sunday as seniors and walk out as alumni after taking part in Colgate's 188th commencement exercises.

Geoffrey Canada, nationally recognized for his pioneering work helping children and families in Harlem and as a passionate advocate for education reform, will deliver the keynote address.

Ajay Chahar '12 now has company online.

The first-year student has been keeping everyone updated about campus happenings through Twitter, a micro-blogging service.

Chahar will still use that platform for now, but his brief posts and those of other Colgate students and staff members also will be presented on a Twitter-like blog called ''gatetwitter.

Ask Ajay Chahar '12 where he is from, and he'll say, "Colgate."

That's partly because he is so excited about being a first-year student, and partly because he's lived in so many cities in his native India that he doesn't know which to call home. His father is an army colonel, and Chahar moved with him from post to post.

While he has traveled throughout India, learning five languages from Bengali to Punjabi in the process, he never had the opportunity to travel beyond the region.
