<span id="badge-medals-widget"> to <span class="badge-medals-widget">

Just for proper html validation:

Please change qa-plugin.php line 415 from:

$output='<span id="badge-medals-widget">';

to:

$output='<span class="badge-medals-widget">';

why is id a problem?

[echteinfachtv]

Because an ID should be unique, a CLASS can be assigned to many html elements.

I am not sure but I found some IDs being used several times. (Cannot remember if the one above is the one / is the only one.)

This is just for proper HTML... minor issue.
