I download a couple of wsp (sharepoint workflow solution) from this site http://www.techsolutions.net/Blog/tabid/65/EntryId/17/Fab-40-Templates-for-MOSS-2010.aspx
and I haved activated my added solution in Site Settings | Solutions with Central Administration, also under Site Settings | Site Collection Administration | Site Collection features, I can see the following three wsp that I imported.
"Web Template feature of exported web template AbsenceVacationSchedule"
"Web Template feature of exported web template ContactsManagement"
"Web Template feature of exported web template CallCenter"
How can I use those solutions that I added to Sharepoint Foundation 2010?
Do I need a new web application to work with it, or I can activate it onto my current Web Application?
