Every time we put out a call for testing - we link you to this
Not sure whether people are aware but, if someone visits there
and at least 1 test has been done for each possible test - they
would see something like 
This tells us a few things:
we've got 5 of 5 tested in both Mandatory sections
we've got 3 of 3 tested in both Run Once sections
we have no optional testcases
It doesn't however tell us how many people have tested each of
the various testcases, to see that you need to enter either the 64
or 32 bit sections - and you'll now see a list of all the various
testcases and how many times each one has been tested.
On entering you might find that each test has been run once - and
while that proves that the test has either passed or failed - it's
done so once for one person.
I'm sure that you'd agree that this is less than ideal.
What we at the Xubuntu Team would really like to see, is more and
more of the community doing testing, but more importantly
If you're someone with a very specific set of hardware then it is
even more important.
Let's get the number of tests run for each option at least into
double figures, recently we've had to release when we've had 2 or
3 test results recorded.
The greater the spread of hardware we get tested the more we can
be sure that the release is likely to be good for more people.
