Sometimes I find searching for a specific topic/question in DiscussCESM forum requires more than a few clicks and have to look for unrelated topics until I find the question I am looking for if there is any. I wonder if search tags just like that used in http://stackoverflow.com/tags will be useful to be included while posting forum questions? Some of these tags can be "clm4.5", "lnd_diag4.2", etc. for land components. Creation of new tags should be limited to administrators to restrict unnecessary or duplicated tags. Just a thought!
