Hey Grievous,
Welcome to the Forums! Good to have you with us. To set any custom pics/sigs or to send PM's you need a minimum of 40 posts. There are also many problems that are being worked out since the updates so we ask you to bare with them for the time being
.
And on a side note does anyone wanna take up my request to make me a welcome GIF to welcome the new members to the forums?!?!
