HI I have a delphi membership.. it charges me yearly.. how can i change the payment plan from yearly to monthly or quarterly? thanks for your help.

I see you have automatic renewal off.  When your current subscription runs out you'll see the quarterly options to sign up again on MyAccount https://forums.delphiforums.com/myaccount  . There is no monthly option.

let us know how it goes  ...

thanks so much gunter. have a blessed day.
