Sadly, Tweet Adder is not free. I am not much of a twitter fan either but it is great when it comes to not having to spend a lot of time on twitter. You can simply set it and forget it and let it do the work for you.
The $55 is well worth the investment in the long run.
Sorry it took me awhile to answer your question, and thank you for your comment Eddy2106.
P.S. - I also wrote a hub on how to get a discount on tweet adder though - Search for Tweet Adder discount on hubpages and you will see instructions for a discount that can save you up to $37... I used the discount and I saved 20%.
There are many social networking software available, if you mean "Tweet FriendAdder" ->link: appcraft.org/shop_tweet-friendadder_181 this tool is not free ($50) but a trialware download is available.
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.
