To Nico, but also to other people reading this who are also unsure about whether they are good or knowledgeable or spiritual enough to join the Reading Workshop, I personally wouldn't let shame or fear ever get in the way of trying to connect and network with others. Worrying about if you're unconsciously influencing others negatively because of your perceived shortcomings just makes you reach out less. Instead you should be reaching out more with questions, experiences, etc even if you feel like you have nothing to contribute. If you have a question and ask it, there's a good chance ten other people have this same question but do not ask for the reasons mentioned above. If you have the courage to do this in spite of your fears, you are already setting a positive example to others and having a positive influence.
There will be Ambassadors Mods present at the reading, who ARE experienced in identifying disruptive influences. I don't address that sentence to people out there intend on doing mischief, but rather to people like Nico who are worried that something fundamentally "bad" in them is going to corrupt or disrupt or ruin the experience for others. If there is something inside a person that is actively blocking proper networking with others, this will be pointed out, and the person will receive a gentle nudge in the right direction, so the experience will be more rewarding for the person and those who interact with him or her on the call. Odds are it's a very minor thing that we can sometimes blow way out of proportion. Like Chu has said before, that can be just another ego trap, thinking we are more power to influence others than we actually do.
