Sorry if this question is already answered/explained somewhere, but I couldn't find it. What does the Members Total Reputation number mean under your user name?

Reputation is based upon status updates. These are your updates that people reply to or like. Idk what the number means exactly but I know that the more you post status updates, the higher the number gets.

The total reputation number is the amount of 'likes' you received on all the content you have contributed to the site. For example, I just 'liked' your question, now your total reputation is a '4' instead of a '3'.

I second what Navigating said. It counts the "liked" content.

And now that @Berry78 also liked your post, you have a total rep of '5' instead of '4'!!

Thanks all! Makes sense now...still getting used to this.
