Rob Land on "Automatic creation of sub-domain or folder"

Hi there,

For a new project we are investigating the possibility to use WP multisite.

For this project we would need to have a tool/plugin that can import (from a .csv) a maximum of 5000 records to create sub-domains.

Is there anyone who has some experience with this? Are there off the shelff tools (plugin) for this pupose?

Any input would be appreciated.

Thanks in advance,
Rob Land
