1) get on to the google groups site and sign in upper right corner of screen.
2) click on your message.
3) look to the right side of your message you should see a box marked REPLY. This is a drop down menu. Right click on the little arrow beside the button. At the bottom of that menu you will see Delete Message.
4) click on delete. Your message should be gone when you exit and re enter the site,
NOTE: YOU WILL NOT BE ABLE TO DELETE ANYONE ELSES MESSAGES. ONLY THE MODERATOR CAN DO THAT. (I have removed all the posts from last year)
I hope that we can clean up the dead posts so that we can avoid answering year old posts. I will continue to delete messages for events that have already happened.
if you need help contact Bob H. I will try to help you through it. I am one of the moderators for our club.
Good luck
