Site Names

In WSS Site Names may not contain the following characters: \ / : * ? " < > | # { } % & " ~ +

You cannot start a site name, subsite name, or a site group name with an underscore (_) character or with the period character (I recommend avoiding the (_) underscore in site names)

You cannot use the period character consecutively in the middle of a site name

You cannot use the period character at the end of a site name
