Hidden documents
Alvaro has uploaded a document:
https://communities.ptc.com/docs/DOC-1132
It doesn't show on the Mathcad home page under "documents" though, and doesn't appear to be associated with any sub-community. The only way to even know it exists is to go through Alvaro's profile. So far, I haven't even figured out how to upload a document so that it is hidden like this. When a new document is uploaded there should be some way for everyone else to know about it!
Nobody will use these communites if we have to check every one of them to see if there are new posts and evey user profile to see who has uploaded something new!
