I'm a sub, and recently started a guild for myself. I paid the people who helped me some credits, but one person was f2p, so I mailed them.
He asked for some help, so I'm helping him do some quests and stuff, and I happen to check his equipment. It's way substandard even for his level, so I go to the GTN and buy some low level stuff, a few adaptive items and send them all to him, including more credits. I tell him it'll be there in about an hour.
About 40 minutes after I started the guild, I get mail. I check it, and it's a mail from him (he's been with me the whole time), returning the credits I sent to him. I'm confused, but take them back. A little while later, I get another mail, this one receiving the items from him that I had sent. He says he never got the mail.
Did I miss something, or can subs not mail stuff to f2p?
