Regarding Bruce's comments below,
Well, and we simply need to remind TSS to add these to the help with search on the forum as a stopgap, as I'm sure we can all agree the peer support forum shouldn't be the primary documentation.
I agree however, the undocumented commands thread (and repeat bump references to it for new users) could be the reminder to TSS to update the help. So all that need be done (once a missed command does reach the help) is an update to the thread that it has been added to the help (at the top most likely). So maybe a designated person (maybe TJ for example) keeps a consistent format for this process. For example, maybe the format could include the approximate date the command finally reach the help.
Aonther thing I have noticed (as TJ has done) is that often the forum refrences provide much better examples of the command than the help does. So the thread examples should probably be kept even when the help is updated. It would be nice if the help had some of these better examples included.
One more thing (and maybe TJ has already done this). I have on my todo list the creation of a searchable list of the URLs that I have more than once directed someone to read (especially if it took me more than 2 minutes to find it). It would be mostly to save me time in finding them again in the future (increasing the odds that I will put out the effort). So from now on I will have it in my reminder system to keep updating this reminder with URLs and "search key words" for the URL. I just created it. The reminder title is called "MC forum URL Search Keywords." and in the body of the reminder (or in a searchable document). The first URL I put in is the one TJ just created.
