Take a look at
http://search.atomz.com/search/?sp-q=ssl+announcements&sp-a=sp100186b4 I had to
tweak a couple of items to use it both with and without https:

I was able to import the web  part but when I try to create a new announcements,
I get this message:

Setting Else Condition oCDODoc.Property
:urn:schemas-microsoft-com:office:office#Title = gsdgs
Err = 424 Desc = Object required

Setting Else Condition oCDODoc.Property
:urn:schemas-microsoft-com:office:office#Description =
Err = 424 Desc = Object required

Setting Else Condition oCDODoc.Property :abstract =
Err = 424 Desc = Object required

Save
Err = 424 Desc = Object required

Does anybody know what this means?
