Thanks for the quick reply – I will give this a go!
Hi – I’m glad to have found this post, as I’ve just been trying to do something similar – ie, xxx.sub.site.com as the child sites.
Unfortunately my hosting provider can’t seem to figure out how to allow for multi-level wildcards – ie *.sub.site.com – the install works beautifully but the DNS won’t resolve to the child sites (the main sub.site.com is fine)
Has anyone else successfully used Multisite in this way that can give me any tips?
