Thank you for this post, Bonny. I tried to sign up using their link and after trying to "pay" them $0.0 via PayPal for the "Free but Professional Trial Account" a number of times. After going through the whole process, PayPal just logged me out each time. I guess, PayPal has received so many scam complaints about IAPWE, that it just doesn't let the "free" payment complete! But, now that I have read your post, I will immediately remove my card details from PayPal and/or any membership that might have been subscribed for IAPWE inadvertently.
Thanks again. :)
