Multi domain, domain mapping project help

Hello all,

I am trying to run several niche portals from one installation of wordpress 3.1.

I am running wordpress 3.1, the latest version of domain mapping plugin, supporter and several other plugins from wpmudev. I am using a sub-domain install.

I have mainsites.com running as the main installation. The jobsite is running as a sub-domain of the mainsite (jobsite.mainsite.com) and this is mapped to jobsite.com and working well.

Now with the multi-domain tool. I would like to build recruitment sites as sub-domains of jobsite.com (jobsite.mainsite.com).

1. Would I be able to build client1.jobsite.com, client2.jobsite.com, client3.jobsite.com?

2. I already have a dns entry pointing the domain jobsite.com to my mainsite ip address and currently just park the domain using cpanel. Do I need to do any more entries or is this sufficient to get it working?

3. Also these sub-domains will be mapped – e.g. client1.jobsite.com mapped to recruiter1.com and client2.jobsite.com mapped to recruiter2.com

That gave me a headache.

regards

TB
