I currently have 9 domains.
I'm thinking about becoming a reseller.
If I start with Special can I upgrade at anytime to Starter?
What would I be losing if anything? And what would I be gaining?
Thanks,
Dean

You can update at any time. You will loose nothing and it will cost you nothing.

With Special package do we know where our visitors came from and from where in real-time?
Do you provide such software?
Can we track visitors in our sites and have background hit counters?
Dean

Awstats and webalizer stats are available in any our package. Using them you will be able to track your visitors. Also cpanel includes counter management and you don't need any software more. But if you wish you can install any CMs from fantastico. The most of them include built in hit counters.
