There are many ways others can find your shared photo blog (first, you must be sure you've shared the photo blog so they can access it.)
1) By Visiting You. If you have shared the photo blog with other KeepandShare users by name, they can find your photo blog by visiting you. They should first make sure you are in their "Friends to Visit List". Then they can click on the "Visit" command in the gray tabs and click on your username, and then click on the photoblogs link:

2) KeepandShare accounts can be visited by typing in by typing in the URL (web address) that includes the KeepandShare username as follows:
jsmith.KeepandShare.com
or www.jsmith.KeepandShare.com
3) Clicking through on notifications on their dashboard. Whenever you first create your photo blog or edit it, your friends with whom it is shared will receive a notification in their Fresh Shares section "Share Central" area of their dashboard. If they click on this notification they will be taken immediately to your photo blog.
4) Receive an email from you. When you are finished editing your photo blog choose the "Save and Email" button to save your work and also email a direct link to your photo blog - your friends can then click on this link when they receive the email.
5) Use search engines. Google, Yahoo and other web search engines will find your Public shares.
