I wish you well on your endeavor. I believe you are sincere and your church comes out of a pure desire to help others.

I hope I am wrong, but I an afraid that you will find your new church will have many of the same problems as the church you left. Some of those problems are endemic to organized religion.

People are united by shared beliefs, so churches get organized around the least common denominator. What is your shared belief? That conventional Evangelical churches are bad? How far will that take you? What about those people who retain many of the abhorrent beliefs the drive people away from the church? Will you exclude them for their prejudice and bigotry?

People are naturally judgmental. It provides them an opportunity to indulge in pride and feel superior to others. Christians are some of the worst as they believe God shares their righteous opinions. They feel completely justified in their negative judgments of others. I don't believe you can run an online forum and keep that instinct in check, particularly with many who remain anonymous. I hope I am wrong and everything works out for you, but I have serious doubts about the viability of what you propose.
