Some helpful tips:

1. Seller could help by putting their signtures:

I will contact you with this/these number/s 0XX XXX XXXX or by PM (LYN) or IM (your nick and the type of IM you use).

2. Buyers, finialise the deal by PM. i.e. Thru PM ask them, Please confirm: Product for RMXXXX and RMXX for postage, seller's real name and account number, your address and contact number.

The Seller should reply 'Confirm' with the above information in quotes.

3. Double check the LYN nick that is replying to you to confirm that it is exactly the same as the one in the sales thread. Double check all phone numbers to make sure they are exactly the same as the ones in the seller's thread or signature.
