Yeah, i'm pretty sure they were sent, allthough i always preview my messages before sending.
I think i found the option though, under "edit options" on the private message tab. Seems "When sending private messages the forum can make a copy of the message in your Sent Items folder." is unchecked by default.
It explains why i didn't find my messages in the sent items folder, so i guess they got through.
If they didn't get through though, tell Arhu i tried to reply
