"Original - II"

You see, I wrote it in ICQ, right?

That's why there wouldn't be such issues with WhatsApp. Like with verification... I'm not receiving messages from you, even though it says you added me as a friend, and I added you too. And my ICQ and Mail.ru Agent are linked to the same SIM card. Are you suggesting I change my SIM card?

Are you suggesting I install WhatsApp, enter my phone number there, and post my WhatsApp account here so that everyone on the Heroesworld website can access my phone?
Why would I do that?

I messaged you on ICQ from home. I'm at work now, and my boss has strictly forbidden me from using ICQ at work, so I'll only see your message in the evening.

P.S. I will only install WhatsApp in one case - if it is explicitly stated in the tournament rules or the website registration rules. Currently, the rules state standard tournament registration, which requires providing an ICQ number when registering on the Heroesworld website. Or, as I understand it, information that replaces this number - in your case, it's an email.
There is no talk of WhatsApp yet. So, we are just discussing WhatsApp out of curiosity.
