Hi, I don't know if this has been posted, but it is getting on my nerves, if you are getting annoyed by the security warning when entering mpgh.net with Opera browser, this is what you can do:
Taken from the Opera site.Enabling/Disabling Fraud Protection
Fraud Protection is enabled by default. It can be disabled/enabled from Settings > Preferences > Advanced > Security by unchecking/checking the box marked "Enable Fraud Protection."
Have fun.
