Antoine Thank you for answering. My English is poor, so I can't explain detailedly 🙁
However, I could give some examples to show the reason.
e.g. for NO.1:
Administrators or other user with permission can give money to the poster when his reply or discussion is good enough.
So this button in dropdown will be more convenient to operate.
e.g. for NO.2:
Let’s suppose here is a user named David, he had 38 Money already.
Now I want give he 235 Money more, I just input 235 in the Text Field which marked + , then click the Save Changes Button, David gets 273 Money.
For another, I want cut he 12 Money down, I just input 12 in the Text Field which marked - , then click the Save Changes Button, David’s Money changes to 26.
That’s more easier to change user’s Money.
It is also make the base for Money Store (User can use Money to exchange for some gifts).
I will make the language file of Simplified Chinese later, and upload here🙂
And Thanks again.
