Go to the top where it says your name, use the arrow and go to 'Menu'. Then copy it from there. If you need the Forum Numbers then there should be a few numbers in the Profile URL, for example, the bold is what you are looking for.
What it means is join Team Speak you have to goto waiting for interview within the NHS Rooms. You don't have to link your TS to the forums however you do need the link to your forum profile. When in the waiting for interview there are some things to read over on the TS room on what you need to have with you before the interview. Hope this helps and let me know if you have any other questions.
