Due to recent announcements, this event will be modified slightly for FTP characters:
If a character is unable to receive items via trade due to account restrictions, their name will be taken down for mailing purposes.
Preferred players (former subscribers or FTPs that pay for cartel coins) will have some trading restrictions lifted, although to my knowledge what they can and cannot do hasn't been specified.
With the launch of FTP on the 15th, the first Arming the Empire event will take place on Friday, November 16th at 8pm, as planned. Come out and grab some free gear!
