The way I have seen it working on other sites is that the “OP” raises a flag on their question when a suitable answer "in their eyes" is found.
This “green tick” in the main question section, indicates to others that the “OP” has found a solution that suits their needs and further solutions are not needed.
This has the disadvantage of not allowing for other, sometimes better solutions to be put forward, as is the case here.
Often the best solution may come much further down the list of proposed solutions and after much discourse.
It does however warn others that “a” solution has been found and that further effort could go to other questions.
The fact that a flag is not raised denotes that a solution is still wanted, and then perhaps others will try and solve it.
There are both advantages and disadvantages to this system of flagging.
It seems to work best in multidiscipline forums where there is a very wide range of unanswered questions which pass away from the main page still unanswered if a flagging system is not used.
