I'm trying to place all the domains I have on DreamHost

hello,

I'm trying to place all the domains I have on DreamHost in one multisite.
The primary domain is mywikipla.net and the mapped domains are all the rest starting with doiwhat.com

1. The multisite looks ok, I installed the Domain Mapping plugin, I transfered the sunrise.php file to /mywikipla.net/wp-content/ added the sunrise line in wp-config.php

I followed the instructions of the Domain mapping plugin until I reached the DNS CNAME settings which example does not match my host's DreamHost.
I need some help configuring it.

2. in multisites I have "sub folder" setup.
in the Domain mapping plugin example, the multisites is based on sub-domain sites. My multisite is configured as subfolder.
Does it matter?

Thanks and regards
Israel David
