HubPages does this for you automatically after you have a certain number of hubs. The titles and the catagories rotate regularly. You probably have to have at least 30 hubs--maybe more-- before this happens.
Watch for it as you add more hubs.
I am sorry it took me so long to get back to you. Rochelle Frank is correct, you may not have enough hubs for them to go into catogories. Once you have enough they will automatically be seperated into like catorgies depending on the catorgoes you choose when setting up you new hubs.
Keep on checking your caterories on your account page and before you know it, as you keep adding new hubs, you will have enough to be seperated.
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.
