I am also very leery about using PayPal in any form. I posted my experiences with them earlier in this thread, and many of my friends in another forum have also cautioned me not to use them due to security problems (rumors about account holder's data not being protected, hackers penetrating PayPal's database, etc.). I have reverted to sending money orders for stuff I order on the Internet unless it is a trusted merchant like Amazon. I also have a protection scheme for my credit card through Visa and my bank.
I have moved in the last few months and I tried to get on Paypal and change my info...bank account, addy, etc. Virtually IMPOSSIBLE. I just gave up. Probably a good thing. Money orders and checks will have to do.
