I made a typo, it is:

<team id="da">
<_language id="da">Danish</_language>
<coordinator id="kristho"/>
<bugzilla-component>Danish [da]</bugzilla-component> <webpage>http://www.fedoraproject.gr/</webpage>
<mailing-list>dansk</mailing-list>
<mailing-list-subscribe>http://dansk-gruppen.dk/index.php?ID=4&lang=da</mailing-list-subscribe>
</team>

please correct this tag <webpage>http://www.fedoraproject.gr/</webpage>
add your Danish home page rather than Greece :)

Here is the correct informations:

<person id="kristho">
<name>Kris Thomsen</name>
<email>lakristho</email>
<webpage>http://fedoraproject.org/wiki/User:Kristho</webpage>
</person>

<team id="da">
<_language id="da">Danish</_language>
<coordinator id="kristho"/>
<bugzilla-component>Danish [da]</bugzilla-component>
<webpage>http://wiki.dansk-gruppen.dk/index.php/Fedora</webpage>
<mailing-list>dansk</mailing-list>
<mailing-list-subscribe>http://dansk-gruppen.dk/index.php?ID=4&lang=da</mailing-list-subscribe>
</team>

Added. Thanks.
