I can create aliases for my Dropbox subfolders, but not the parent folder.

First, I'm not sure what "a shortcut to a web link" is actually.  I am familiar with creating links that I can copy and paste into emails which bring others to documents or folders that I want to share.  Is this the same thing?  

Second, I have a question about step 5 under creating a shortcut to a web link.  It asks me to "enter the URL" and Name of my shortcut.  What URL should I use?  How do I know if it's correct, etc?  Please advise.  I would attach a screenshot here but I still don't know how to do this in the chat here...  as I mentioned above the camera icon does not allow me to simply select and image to place here or drag and drop, it asks for "source" and dimensions etc.  and I also don't know what that is.  Seems like this should be easier.  

Lastly, I must say that I once was able to create aliases or shortcuts on by desktop to DB folders and now not being able to, greatly decreases the value of the Drop Box app in my opinion.  So I do strongly recommend working with Apple or others to figure out how to get this feature back and integrated.
