Got the same problem, the game seems to recognise and autocomplete the commands /off and /officer, but when I type that I just end up in normal guild chat. Also in the channel selection it only displays guild,say and zone. I do have permission in the guild settings to use officer chat.
You need to spend those points on skills you already have to improve their rank. Each skill has 3 ranks, 2 of which are available at that point. The third rank of all skills is unlocked at 20 points along with the next tier of skills.
A bit more feedback on the 403 error: I don't have IE installed (removed the windows feature) so I don't get the second window with the res:// address that others are getting. It still shows the 403 error in the launcher window though.
Getting a http error 403 page now in the launcher after entering my login info. We are supposed to use the e-mail address as username right? EDIT: sorry for the double post, didn't see that my first attempt at posting worked after all ><
