Sorry for the late reply. I asked a few friends and they really enjoyed the talk. They wished that the program could start on time though - it started about 1/2 hour late again, and pushed the whole day's schedule back, because many people were late. It is not fair for people who came on time and had to sit and wait. I understand that Howard did not want people to miss worship, so it might be good to arrange some icebreaking/game time in the first 1/2 hour if we will still expect latecomers in the future.
One sister told me that she particularly likes the last part of Dr Lin's talk (about "after dating" - how to deal with breakup, crushes, etc) because it is not talked about very often. I also agree that it is more important for our target age group. I suspect that many people in this age range (especially the more mature guys) are still single because they have past relationships that they could not get over with. Or they might have self-image problems... which is another very good workshop/discussion topic in the future (more like identity in Christ).
