Filtering of user input before sending per email?

Since you are expecting only comments and suggestions, you can simply remove any characters other thant alphabets, numbers, and ".", ",". Even if it removes other characters it wouldn't matter to you, you would get to know what they mean. The "=" is the biggest enemy.

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.
