I just noticed that there is a feature-request tag on the main site. Putting up a tag wiki on it that says the tag is not appropriate for Stack Exchange is not a good solution for that. The very existence of the tag will encourage such "questions" and most people will not notice (or will ignore) the tag description.
I've removed it from the two questions that have it now and rejected the wiki edit (sorry, Doc Walker). The tag will age away on its own in about 24 hours and I strongly suggest it does not get resurrected. If it keeps coming back, we can talk about blacklisting it altogether.
The official SmugMug support forum is definitely the right place for feature requests and if a question is posted that cannot be answered with the existing feature set, "it can't be done, but feel free to post a feature request on the official forums" is a valid answer.
