For the college students pining for the good ol’ days when Facebook was only for them: CollegeWikis, a group messaging and info platform, has closed a $2 million round led by HighBAR Ventures, with participation from Richmond Management, eCoast Angel Network and Boston Harbor Angels. Since its launch last year, the NY-based site claims over 50,000 users in over 200 colleges. Students with “.edu” e-mail address can sign up for the free service and can then join groups, such as for certain courses or dorms, and send and follow messages to group members. So far, popular topics include “Tips for incoming freshmen,” “Favorite restaurants,” and “Installing stuff on computer lab computers,” though nothing on beer pong yet. Release.
