i will second this.
usually, 2cents is very reliable, but it does go through
spurts where it just stops crediting. you'll even reach
the last "you have successfully finished the survey"
page, so you know it went through... and then nothing
i even leave the page sitting there for a little while
(as another user suggested to do) but when 2cents
is going through a spurt, nothing helps. i usually don't
touch it for about a week, then come back to it and things
are fine again.
its a love/hate relationship, unfortunately.
