The blog is still TeachingCollegeMath, but it's relocated to the domain www.teachingcollegemath.com.
All the posts and comments have been duplicated on the new site.
Maria think the new site is easier to read and navigate. The text of posts is now in black (instead of white on black).
On this site you can find all sorts of resources for math, technology, and teaching. The site should be very helpful for anyone who wants to incorporate Internet materials into their math courses.
Go to www.teachingcollegemath.com and enjoy!
