The name of your site is extremely important. Stick with names that are easy to remember and spell. Most commercial ISPs will register and host a domain name for a small fee. Chat it up. DO NOT approve vendors using them for talking about a product or server, unless it in response to another person's inquiry.
Content is king.
Keep in mind that better content makes for a better Web site. Take it easy. One of the most common mistakes people make when marketing online is to use techniques that come across as pushy. Keep promising something new. Your Web site should constantly promote what's coming up in the near future so users will return again and again.
