  I think in your first message you said you're using xastir.  Within 
xastir, simply right-click anywhere on the map, and select 'object/item -> 
Create' then fill in the form.
   You don't have to be at the digi to put a digi object out.  In fact, we 
are sometimes entertained by someone with too much time on their hands 
placing an 'array' of objects out in some remote corner of the world in 
such a way as to spell out a message.  An APRS 'easter egg' for those who 
stumble upon it...  A gentleman I met at Dayton last weekend admitted to 
flinging objects into the virtual Nevada desert (area51??) spelling out 
the brand name of his favorite radio manufacturer...
   For a repeater object, refer to Bob's document that you already found 
for naming convention, symbol choice, and comment text format.
   It would also be wise to contact the repeater trustee first.  In some 
areas, repeaters have been vandalized when their exact location becomes 
known, so it may be wise to encode the object with some position 
ambiguity.
