I just participated in a question in which the author found the solution with my help. He'd like to accept his answer and use my answer as an assist and "split the points". It's not uncommon for something like this to happen and then the question just hangs around for a 4 day waiting period allowing any contributor to object. However wouldn't it be nice if there was also an option for all contributors to accept thereby shortcutting this waiting period? Sort of an opt-in approach.
