Maybe give the users the oppertunity to
say wether they accept one or more of the
posts as the answer to their
question/problem or that they have the
solution to their problem.
This would most probably be just a normal
"Mark as locked" thread but in a more
"User Friendly" manner.
This will also help in terms of
1. Housekeeping (From a
supporter/moderator point of view) so it's
known which threads is still on-going
(wether it has become a "chat" thread or
no one has ever had an answer to the
specific question).
2. Expand the search facility to allow a
search on only "answered"
questions/problems.
The downside to this however, is that
others can not reply and say that they
also have the same problem and that they
are glad to hear of the solution and/or
that others has the same problem, unless
you can make a change so there is an extra
flag of "Answered" and not necissarily
"Closed" on the thread, which would still
allow for "Thank You" posts and/or allow
the thread to "mutate" into a "chat
thread"
