Submit POI changed a number

[Amiranda]

I was attempting to submit my first POI (in Nek Forest). The submissioin form changed a number, resulting in a location on the opposite side of the map. I think there aren't enough spaces in the form. I tried submitting it with and without commas between the three numbers but that resulted in zeros (0.00) for the second and third numbers. The number I was trying to submit is (-707.54, 81.04, -1,606.02). The form truncated the third number and moved the decimal point to 1.60.
