Welcome to Atheist Nexus with its 8300+ good friends.
I hope your new group gets members and succeeds (I am too far away, in Bradford-on-Avon (near Bath) and Oxford--see My Profile)
A useful existing group to join, with its 132 discussions and numerous video films, is “ORIGINS” (Origins: Universe, Life, Humans, Evolution, Religion....).
One discussion (72 posts) is "Proud to be Atheist". There's much to feel good about
because atheists and humanists hold the intellectual high ground——far from the mental slavery of superstitious people who submit to a narrow-minded controlling clergy with their imaginary god, fictional heaven and non-existent hell.
