In the various forums i have perused and at times contributed to, of course i have seen topics veer of course and become something else. This is how conversations go in real life. I dont really see the problem with it. Isnt this what we are doing having conversations, only in print? If the person who first posted wants to post again to bring it back around , that is all to the good, but i think driftis only natural and actually may be good because it brings in other points related to the original topic.
