Received Nem Without Message

Hi, I just joined this Forum and read about send/rev Nex with message topics. However as I am not a pro of tech issue, quite a dummy actually, I had a question:

I had purchased Nem from changely(actually I forgot exactly where did I purchase) and had them transferred to my Nem Wallet without a message. As I recall, when sending they popped up a message similar like:[ if you send a message but the recipient does not support a message, then your money will be lost. ] As I am not sure Nem supported a message or not; plus I did not know what to put in the message, so I did not add anything in the message box, and I received my Nem in the wallet.

So, if I did not cross these message attaching problem, I will never know it was required at the first place. Now, I got another issue, I still do not get it what to put in the message? will it pop up automatically or what? I did not see anything relatted to message in my account… annoying.

I know this is a been-asked question, but please help me out so that I know how to do it correctly when I want to sell them. Thank you so much!

Some exchanges, like poloniex, request special message when sending nem to the exchange.
Normaly you dont need to put in anny message when sending nem. Account and amount are enough.

Great! Thank you so much!
