site with just rails issues answered?

i was wondering if there is any site that just lists solution for
problems. google groups is great in getting answers but sometimes you
have to sift through a whole conversation and sometimes not find the
answer.

i have not been able to find any site like that. if there is not, what
do you all think of having a site for rails that would be just
problems with answers. one would not be allowed to list a problem on
there unless they have a found a solution to it. it just seems like it
could be a nice resource for answers and nothing else but maybe that
is just me...

StackOverflow, while not Rails only, has always been a useful resource
for me.
