Does anyone know how to delete all matches?

How do I remove someone from my Mutual Match list?
If clicking on the wee box next to their name on your
MutualMatch list does not remove them, you can use this:
http://mingle2.com/mutual_match/delete_connection/XXXXXXX
where the 'Xs' represent their user-number.

To get their user-number, it is the last digits on their
profile page in the address box, replace the 'Xs' with those.

If you do not have an address bar, right click on their
activated) user-name on their profile, click on 'Properties'
on the drop-down menu, and take the user-number from the URL
(link) provided.

However, I suspect you mean those on your POTENTIAL
Mutual Match list, that you have not clicked Yes, No or Maybe
on..if tis so, you must click on them one way or the other
for them to go away.
