Hide Site Actions
By Anatoly Mironov
The easiest way to hide Site Actions for a specific audience is to wrap this into a SPSecuritityTrimmingControl. Locate in your master page. Paste this before span element:
<SharePoint:SPSecurityTrimmedControl runat="server" Permissions="ManageLists">
Find the ending element and paste:
</SharePoint:SPSecurityTrimmedControl>
