I've made ??a new installation under one domain (let us call it http://domain1.com) with WordPress 3.3.1 (German version) and the plugin multi-domains.
Everything runs perfectly up to this point.
I want to create for this domain (http://domain1.com) an custom blog registration page (like it is done as sosblog.com) where visitors can register their own blog (as a sub-domain). The Registration will be limited by time periode and payment (possibly with the plugin pay-to-blog).
I host on the same server, a small number of other domains
that I can easily redirect to this installation.
The main domains should remain by me as the super admin reserved.
Can you describe how this can be done and I can create this custom registration page?
