I will go ahead to send cards once Dundo responds to this thread. Also to point out, while I'd normally oblige to send first due to my <10 feedback, it comes to my attention that this such user does as well - as FAIC, should both trading participants have less than 10, there is no obligation for one user to wait to receive from the the other -- BOTH <10 USERS MUST SEND AT SAME TIME.
As Dundo was yet to respond to this thread, I decided to wait to send the cards on my side of the trade until I received the side of the trade from him. Result all clear - did receive his cards so I then sent of the ones for him. Dundo will probably still need to respond to this thread so I can grant him positive feedback and hopefully he'll do same for me.
