I can understand anxiety-as that is there during any business decision and I will do what I can to help alleviate it.
Gmail is what I use to communicate with the co-op members. I have over 100 members and you can see from the testimonials on the sales letter that they seem to think highly of me.
With the number of members I don't give out my phone number...if I did I would be spending my time fielding calls and not helping the members by improving the software and the co-op. I do have a corporate number however I rarely use it. This is an online business so all communication occurs one of 3 ways.
1. Forum
2. My Support Team -I have 3 full time support people and several more part timers. All of which are accessible 7 days a week via the support desk
3. My personal email for any other issues that need my assistance.
This system has been my daily obsession for years so I can't reveal a site. I must protect the system for myself and for the members. When you are a member you will appreciate this.
As far as other expenses-this is the standard notice I send out before I direct you to the page where you can order:
"After that is done we will give you the details about the servers needed-as stated on the site you will need 1 server that will hold WCB, and another server that will hold the sites you build with it. The dedicated box we recommend can hold 1000 sites, so it only costs about .20 per site per month ($200, the 2nd server costs about the same).
Also the last thing you need is a $25/month account with a vendor we use."
How many TLD's depends on your budget. We have members with 10k sites and others with a few hundred. You can use our preferred registrar or your own.
