If you list the meetings you attended, and can do so with an clear conscious, all should be well.... really you'll be fine.
Mark, I just got off the phone with the court clerk, again. She has a different opinion than you. She says the judge will not accept anything other than the original signatures on the original card, otherwise sentence will be imposed. Now she claims this is because others have "tried that ploy," and the judge just doesn't want to hear it. Looks like I'm in for a 30-day vacation at the local lockup.
