I will give some small help concerning security, maybe some will find this useless, but it may help.
#1 NEVER STORE ANY SENSITIVE INFORMATION ON YOUR COMPUTER
(so like e-Cash account passwords, e-banking passwords etc…)
#2 Desactivate the “Store Password” option of your browsers and better use something like RoboForm (which is more secure, but not perfect) or other to automatically remind login informations
#3 If you end storing passwords (OTHER THAN VERY SENSITIVE) on your computer using a spreadsheet, always encrypt it and never leave it “clear” (only when you work on it), search for encryption software and PAY for a good one
#4 Never use a computer without a good firewall that detects intrusions
#5 and a last one I’ve forgotten: Always keep your computer clean of malwares, spywares, dialers etc… run good programs that you’ve PAID on a regular basis
#6 As for creating passwords, whenever it’s possible, at least use a grand minimum of 7 characters. 10 or 12 is better. Also, never use combinations of words/names/dates etc… I’ve seen big lists of these words from hackers (not that I have links to them…), used to attack websites. Use a password generator that generate 100% random passwords, with letters, numbers, in caps or not, etc…
I just hope it will help a bit. 
It’s just the minimum to have something safe. Internet Protocols like SSL are actually strong enough to turn down the small guys that seek to steal a few thousand dollars.
Other than that, Donkeystyle, I’m sorry to hear this and depending the business you’ve done with Neteller, they out to have a better stand and refund you the money, hey they make millions of dollars with YOUR money.
