I have often set the Tag-Filter in the Close Votes to c# and .net and silverlight to filter for questions with a technology where I am more confident with and can better determine if a question needs to be closed.
But this setting does not filter for question that use .net-4.0 or silverlight-5.0.
Please allow the wildcard (*) to be used in the Tag-Filter in the review queues, so that I can specify silverlight-*
(as an example) as a filter.
