I'm new to Marketo, but as I've been attempting to read up on various subkects I'm encountering some dead pages. For instance, a search for "subscription management" turned up an item labelled "Marketo Lead Management Fundamentals Training", but when I click through the page fails to load:

If there's a means for cleaning up / removing some of these artilcles, assuming the content has been retired, that would be helpful.
