Rise component character limits

Hi - 

I too would  kindly request that you provide a single location/file/document that lists the various character limits for each of the different Rise components. Often times, users are not writing content inside of Rise, and it is a waste of time to have to track down character limits that are scattered across the site or the internet in general (or missing altogether). It couldn't take long for a knowledgeable Rise staffer to compile and share, and it would save everyday users considerable time and frustration. Thank you!
