@Ced I recommend that you ask in the general room or post a question on the site, or both. This room is specifically for reviewing and improving content on the site. Also, as a separate matter, you'll need to give more information that you have in order to get an answer.
Feel free to ping me in the general room by writing a message that includes the text @EliahKagan, and I'll try to reply and ask for some specific details about your problem that might help in getting an answer or should at least help for writing a question about it.
But I mean, if you want me to see a message that you post, then you can include that. Even if I'm away, I'll be notified and try to take a look. If you're willing to move the discussion to the general room now, then I can try to help you now.
(There are other possible alternatives if for some reason you don't want to use the general room, but there's a major benefit to using it: other knowledgeable people should be able to help you too, and some of them know much more than I do about VPNs in Ubuntu.)
