Give users permissions on item in other list?

As far as I know there is no standard way of setting permissions on certain items in Sharepoint. Only on whole list. If you want to filter combobox - you need to implement custom form (Application Page) and filter combo in your code.

In SharePoint 2007 item level permissions are supported.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
