ok, so i paid and got a RM2K reference..but as i read the newbie board it seems Date Check or P411 is more acceptable.  Did i screw up? Or any of the 3 ok? what is the difference between the 3?

what must this be so difficult.. i'm going back to
amsterdam!

It is accepted in many places.  Date Check seems  most used in Northeast.  Preferred411 is also popular in many cities. Where do you usually hobby?

So you think i should also go with P411?

Txs for the help.
