Ok, I tried WordPress MU, but the problem is that it REQUIRES me to create a subdomain for every new blog. However, I don't have the option to create wildcarded subdomains because my DNS is hosted on my webhost's server. Thus, I don't have the option of making them. Does Lyceum require it? It gets annoying, and only Movable Type allows me to choose if I want a subdomain or a directory based when creating new blogs.
