I would like to be able to create blogs with another dot in the sub domain. Basically a dot in the username.
So the main installation would be .domain.com and I could create sub domains like:
uk.sub.domain.com
uk.sub1.domain.com
au.sub.domain.com
au.sub1.domain.com
ca.sub.domain.com
ca.sub1.domain.com
Without using a multisite install plugin, and without using the domain mapping plugin, is this feasible?
