Yes but you can only mention an individual website twice in any one hub otherwise your hub will be flagged as over promotional.
One thing I do not like is if you add an RSS feed of one of your blogs, it counts EACH item as a link to your site and will flag it as over promotional - although its kind of dumb to have an rss feed with 1 link ... these should not count - each RSS module should count as 1 link. I am not talking about putting up 10 things, usually I keep it to 3 or 4 but cannot even do that, and yes the RSS feed is related to the hub.
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.
