How do I send an email using my address book?
 

Sounds simple, huh? For some reason, I cannot make it happen. I do a monthly publication and send it out via yahoo until my website is up and running, yet last month when I went to send my message, I clicked on the "insert addresses" link and was taken to a list of my contacts. I chose the category associated with my publication and clicked "Bcc" like I always do. Nothing happened. Repeatedly, I tried to insert these addresses and repeatedly I had issues. Ironically enough, I did manage to get them to insert 3 days later, but I have no clue what happened or which planets were aligned to make that happen. I sent yahoo a message and was given absolutely no assistance, save for an email that was sent two days later telling me to do what I was already doing, as if I were an idiot and could not figure that out. Can anyone help me?
