Just noticed a question that was tagged as [web] [missing] [part] (yes, 3 separate tag). The question is WebPart Does Not show up in GalleryWebPart Does Not show up in Gallery.
I have edited/corrected the tags on the question, but I wonder what to do with the MissingMissing tag. Should we leave it, improve it with a description to give it some actual use or just leave nature do its course and let it be pruned by the system if no one will use it?
