It would be very helpful to add a field to the contributed RPMs list that indicates what version of e-smith the RPM was tested against.
This is not a request to supply a list of supported versions, just an indicator of how old the RPM is. For instance:
MyGreatFeature tested against e-smith version 3.0.2
AnotherFeature tested against e-smith version 4.1.2
YourFeature tested against e-smith version 5.1.2
