I was on mpgh.net and wanted to test the security level there...
None ! :/
When you login, your password and login are CLEARLY VISIBLE AND READABLE !!!!
You can try it if you want on my account. (Change my password and I'll hack you :P)
the %23 means it's a #.
Warning, do not forget the last 8 near the &.
I HARDLY recommend to mpgh to correct this breach.
Best regards
