ACM, AFM, AIM, AGM titles

..

The Arena online chess service is offered by a company working with FIDE.

The "titles" aren't the same as titles granted by FIDE for over the board play and don't count for much of anything in the real world. They don't count towards getting a real over the board title.

I think you get a certificate if you pay for it.

From their site:

• Once you claimed it and paid the FIDE fee, you will have this title for life. It will reflect on your FIDE profile and Arena pages as well as at the OTB tournaments.
• You will also get an official FIDE certificate over email.

I'm am a AFM tho

What’s dis

Hello,

I am planning to buy the FIDE online arena subscription and gain one of the following titles: AFM, ACM, AIM, AGM.

I am confident to get at least ACM and my concern is if it works after you stop your subscription. When it gets FIDE recognized, and I cancel the subscription, will I lose my title?

Best regards

FIDE Titles of the lower rating band are valid for life, however acquirement of a higher title described in 1.1 replaces any title reference of a lower status.

Why should you care what happens after you cancel your subscription to FIDE arena?

These A"something" titles may be printed at your FIDE profile and make you feel good, but they are completely worthless outside FIDE Arena.
