Even if it is not Tefilat Nedava, davenning is not a simple thing. Various kavonnos are needed. I will mention HaShem’s names many times. Since women are not obligated to daven, perhaps they should not. Do we have sources for this issue to help me CMLOR?
What is the rational in suggesting that a person who wishes to pray to Hashem outside the context of formal communal prayer, that they may not use Gd's name in doing so?
This seems to me to go against most of the examples of prayer we find in Tanach and the Talmud, as well as Chasidic custom.
