Hello @Raul116,
So as the person you address will be notified of your response you should type "@" and then select their name from the list. Otherwise they may not see your response or question.
One other suggestion is to turn off capitals when typing. Capitals make the message feel like you're shouting.
One way to adjust your price to be the same for each date in a range is to do it from your calendar.
Click on "Host" and then on "Calendar".
Then click on the first available date whose price you wish to change.
A window will open on the right.
In its "Selected dates" box click on the date to the right of the arrow and choose the last date whose price you wish to change.
Then enter the price for this date range in the "nightly price" box.
Now click on "Save".
Steve.
