I like this, Arisara. I have bookmarked it as a reference. I used to think the homepage was also the landing page. This has now been cleared up for me.

One thing that I find interesting. I notice that in some of the descriptions, for example, unsubscribe, the same word is used to give the meaning of the word. If a person does not already know the meaning of unsubscribe, they would have to use context clues.

What do you think about this? Thanks for this compilation. It will certainly be of benefit to me.


Wow, Arisara. Very nice, indeed!
