Hi CiviLydia, thanks for the clarification. I believe, though, that you should stick with the convention of "Like" instead of "Good". This question of what it means is a reasonable one, and though you've explained it to Sarahb well, there will be countless people coming to this site in the future who will hesitate at the obvious ambiguity. "Good" introduces unnecessary complexity. "Like" is already understood almost universally.  

Please consider erring on the side of keeping it simple and understandable and making it as easy as possible for people to express themselves. 

Great commenting system otherwise :-)
