B'nei Mitzvah Planning

We're just beginning the Bar Mitzvah planning process with our oldest son. He had a bris on day 8 and a conversion in the mikveh when he was a few months old. Now we are talking to him about his Bar Mitzvah as a conscious choice on his part to accept his conversion and make an active commitment to living his life as a Jewish adult (!) male. I'd love to compare notes and pursue an online discussion with families who are in the same place or who have been there/done that...
