Why do some of my hubs appear with a light blue font and other with a darker blue font?

They appear initially in bright blue. After you click on them to edit or whatever, they will appear in gray. I'm not sure what circumstances it takes for them to return to bright blue, but in time they will.

If you're trying to open each one systematically, the color can be helpful.

As others have said, once you visit a hub it goes to light blue and returns to dark blue next day or after you sign out.

Because the darker ones you just visited them. The light blue ones you haven't.

As the others have said, recently visited is dark blue, not visited or inactive is light blue. If you have taken a while to visit that hub it will return to light/bright blue.

Yes as said if you click on them and view them the link will change color showing you have been there. If you delete your temporary internet files in your browser all the links will return to the original color and appear as though you've never visited them.

It means you've clicked them before. So don't panic. =p.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
