Before you or humans engage in public Disclosure, it would make sense for you to make as many individual contacts as possible, so you would have individual supporters on the ground by the time of Disclosure and Contact. Some of your contacts you will likely want to keep secret but some of contacts wouldn't mind be less secret. There are already plenty of people who have been in contact with aliens in person and via channelers who don't hide their support for aliens. Some may not advertise their support but they wouldn't request excessive secrecy. Many people would risk low secrecy for the pleasure to be in contact with you.
Obviously, you are already using channelers to speak to people. This effort is pretty minimal and I recommend expanding it as much as possible.
Talking to you in meditation and dreams is another method of contact.
Next, it would be great to communicate to you by email. Automatic typing is a good method. Also, you may be able to have a dialogue with a contactee on a computer screen in a text editor. A contactee would type in a message, and you would type the response. You could also create text files in our computers as response messages. Email feels most natural. It has a security flaw, but not too big. Many questions discussed with you are not harmful if sneaked upon by MIC. Abilities of MIC to control and to threaten people are limited. As their databases of contactees grow huge, there would be little they can do.
Many contactees would want some small miracles as proofs of your physicality. The contactees would believe that you are really aliens or spirits from other dimensions, but for them, it would be essential also that you can manifest physically at least some physical miracles. This would prove to them that you are capable of physical actions. Miracles could be very simplistic. Say to create writings on objects or plants in presence of the contactees. Creating crop circle on demand. Levitating small objects. Bending spoons, transforming rigid objects. Turning light off and on (make sure not to burn their computers, they are easily burned by surges of electricity in power outlets). Holographic appearances are very powerful, especially when observed by more than one contactees. Important are doing things on demand and reproducibility of the effect. We come across few miracles in our lives, but most of them are irreproducible. If miracles happen on demand of contactees and are reproducible, these would be extremely convincing. People would be much more cooperative, if they knew that you are not only powerful spirits but actually can manifest physical actions in our dimension.
