I joined at your bounty campaign though I am not familiar with the Campaign Manager but I think he has a good reputation in this forum. He has 8 positive trusts which I think the basis of a good and reliable person. Hope that you will manage well this project because arizn is a promising project. Therefore, its up to the marketing side to give their effort on spreading their platform.
