Just a suggestion... It might have made more sense to post your question in this thread if for no other reason than that when you do (and since Mark's wife had posted there before), an email will go to Mark's wife and she'll know someone here is wondering about it. In the past, that has caused her to provide an update. On the other hand, it just occurred to me that maybe you didn't do that because you specifically didn't want to bother her (which is a considerate thing)... in which case, just ignore this suggestion.
Re: Just a suggestion... True, but I have never been accused of having sense! Actually, it didn't even dawn on me. Thanks for the post and suggestion.
