I'll add your Reviewed-by tag then.  Thanks.

I suppose everyone is different, but I *really* like seeing "Reviewed-by" and 
"Tested-by" tags on a patch since it indicates that someone who is not the 
patch author has looked at and/or tested the code separately and found it to 
be good.

To me Acked-by usually just means that the maintainer, or someone important to 
the effort, gave it a passing glance a said "ok".  Ack's are important, but I 
give a higher weight to the reviewed and tested tags.
