It requires that your computer can handle java. I have a Din Timelines message board which I will be using to answer questions. I will try to answer questions as quickly as possible. I have an email address up which can be used to ask questions. When you send me an email let me know what era we are talking about.
Some subjects span hundreds of years.
I will answer emails as quickly as I can. If you want to contribute an essay or information to the timeline please email me.
