Closing old blog/wiki sites. Update

As was mentioned in an earlier IT Status post (over 3 months ago) we have several old and apparently abandoned blog and wiki sites on blog.math.toronto.edu and wiki.math.toronto.edu.

Since we received no requests to preserve any wikis we will be shutting down that server in the near future and all data will be completely removed and no longer available.

The only requests to preserve blogs were for the Graduate blog, the Undergraduate blog, and the IT Status blog, so only those will remain.
