Hello, friends.<br><br>We&#39;ve created a shop sign in sheet, which is great for capturing some numbers, like how many people come through the shop during a particular session, how many were volunteers, how many were kids, etc.&nbsp; What I&#39;m having trouble tracking is the number of unique people accessing the shop over a period of time.&nbsp; In other words, I don&#39;t know how to factor out repeat participants when I start adding up numbers from session to session.&nbsp; Has anyone developed a good system for tracking shop activity?&nbsp; What kind of information do you ask for on your sign in sheet?&nbsp; Do you have another system, like tagging the bikes and having tags collected when people complete their projects?
<br><br>Thanks!<br>rachael<br>
