Well, using "_" is not so friendly to users, so I think using "-" is better (check seoMOZ beginners guide).
Well, using "_" is not so friendly to users, so I think using "-" is better (check seoMOZ beginners guide). Also, you would like to check what characters really need escaping on RFC 3986. If you are using PHP, check out urlencode function page at php.net.
I wrote a function to make this updated conversion a few months ago ;) But getting back to your main question, do use escaped (when needed per RFC 3986) for writing your URLs. It is the safe path to not getting stuck or penalized.
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.
