@Bruce Alfred - If you lock objects that contain hyperlinks, all users should be able to click on and activate/go to any hyperlinks - this would include text, shape, web page thumbnails, sticky notes, etc. - basically an Miro objects that are not documents.

If you have embedded a document I to the board, this should also work for those too. I would try locking a document (a d all other objects listed above) and access the board as a visitor in an Incognito browser window and trying accessing these locked objects as the visitor while you are accessing them in the other browser window as yourself. 

I can't test any of this at the moment as I have a three-month sleeping on my lap

Thanks so much @Robert Johnson! I greatly appreciate your help. I followed your instructions, and tested it, and all good. Ran a new workshop today, and had no problems. 

Thanks again!

Best,

Bruce
