Thank you for your contributions for the ClassSpaces design. I very much like the logos you've submitted, and will be starting the branding for a similar service, geared toward small to medium business, in about 60-90 days. Entry #77 from this contest could be a very good fit for that.
When I do post the next contest, I will send you a message here and hope you'll participate with at least that design.
Thanks,
-Gary
