Of course, I would not argue with that.  I thought that un-marking these 
forms as obsolete, and thereby removing the warnings, would merely be a 
reversion that would not constitute a change in functionality, i.e. it 
would not risk any breakage, so it would be a safe change to make at 
this point.  If that is not the case, or not in your judgment, I won't 
argue with you; and I would ask that the change be made in the following 
version.

Thanks,
Adam
