[Loadstone] Questions

[Jeff]

I have a couple of questions.  First, I am having trouble deleting a point 
that I created.  With my GPS enabled I have gone to Exploration Mode and 
moved to the point, and when I press the pound/hash key followed by Key 1, 
my choices are from commencement, saving, save using current or update. 
There is no choice to delete the point.  Isn't there a way to delete the 
point?  Also I am unclear on how to import new maps without including the 
original map.  I know when you first load the program that there is a 
default file under system/apps/loadstone/databases.  That file is empty of 
points until you create points or until you import a map from the point 
share on-line server.  Now if I import a map from my local area, and then 
later import a map from some other area that I will be visiting, how do I 
keep from importing the maps together?  Another words how do I deep my local 
map separate from some other maps?  I know that depending on how big the 
database file is it will take longer for Loadstone to access it.  I hope my 
questions are clear.  Please let me know if you need more information.
