NEED HELP CONSOLIDATING GROUPS

Mark,
My issue - Following a terrific Masters competition where I created the group "Trivest Masters", password "trivest", we decided to also do a pool for the U.S. Open. I inadvertently thought that all users would be able to choose a new group to join, so I created the "Trivest Open" group, password "trivest" and resent invitations to the whole list. What happened, unfortunately, is anyone who had participated in "Trivest Masters" signed into their existing accounts and were sent back to the "Trivest Masters" group where they made their Open picks. For those new registrants, they chose the "Trivest Open" and made their picks there. As we had about 75-90 new members and 75-90 returning members, I suddently found myself with 2 seperate pools with roughly equal numbers. As a quick fix, I manually created new accounts for everyone in the old "Trivest Masters" pool and transferred their picks to the "Trivest Open" pool so that everyone was in the same place. This worked but clearly was a suboptimal solution...

My question - Can you delete the accounts for everyone that participated in both the "Trivest Masters" and "Trivest Open" pools? This way, when I send an invitation to my same big group of people, I can tell them to simply reregister with the site and choose a new group I'll create for the British & PGA. Alternatively, you could perhaps just delete these groups so when the people sign in they will have to choose a new group.

I look forward to hearing back from you. Everyone that has participated to date has absolutely loved your site and the pool and I'd really like to continue it for the other 2 majors. Unfortunately, however, I'm not sure how to fix the mess I've created without your help.

I appreciate your time and help,

Todd
