I want to revert back to original yahoo setting?

Before, I had a CHOICE to upgrade my yahoo mail. Today I HAVE no choice.

I tried it..... I HATE it.

It has slowed everything down

Takes an AGE to get into mail, and even then sometimes NOT.

It keeps closing down

I cant copy & paste into new messages

Its not remembering my sign in

EVERY *&^%$ Time I have to start over

Im getting SOOOOOO stressed out

I tried phoneing, then found out it was a BOSTON number. geeeeezzzzz!!!!!

Before I throw this out the window, can some one tell me .........

HOW DO I GET BACK TO THE ORIGINAL YAHOO?????

Oh yeah..... another thing .... this is the THIRD time ive tried to post this!!!!!!!
