You can share links with everyone in your Troop or Pack using the Share badge. You can save a new link by clicking on the Share badge then selecting the Recommended Link option from the drop down menu box as shown below:
seems like creating recommended links is broken. I tried creating a new link and it keeps telling me that it must be a valid URL? i even copied an existing link that works and still receive the same message.
Are you trying to link to a URL within TroopTrack? I tried that once and got a similar message. Apparently the Recommended Links page only allows external links.
I was trying to link to merit badge work sheets at usscouts dot org and it didn’t like it. I had to link at the home page and then in the description explain how to navigate to it
