Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Yes sir, go into your User Control Panel and enable them. That will place your sent PMs into your Sent PM folder within the Private Message display. A copy of all Sent messages will be placed there from now on until you disable it. They are not enabled by default to save your Sent PMs. Don't panic, your messages more than likely got sent, you just didnt have the option enabled to save your sent messages.
