Tibor Monostori has launched a new website [link], covering a wide array of topics including Open Theism.
An excerpt from his article on What is Open Theism:
Open theism is the doctrine that God can be perceived and experienced through space and time, since He exists in space and time and that He is open to and strive for a mutually loving relationship with groups and individuals. The future is not determined, but open and what happens around us is the result of fully or partially free will choices of divine and human beings. God reacts to His creation. It is also called relational theology.
