People make this level harder than it needs to be.
When you get to this level, you earn the ability to Pimp. Use this new ability wisely.
Making status requesting newbies to send you a drink, or comment your profile, will not be seen by newbies.
The embedded link to the newbie page is really the best place to start. Some will get lucky with quick responses, some won't. I would go to each profile on each page. Rate/Like/Fan/Friend them all. Leave a friendly profile comment. Send them a gift, which is up to you. A glass of wine or fuweiser starts them on their drinks achievements. Sending something from the seasonal or love and friendship page isn't a bad idea, but limit it to the friendlier ones, not so exotic, unless you want to take your chances.
Don't expect immediate response, keep doing this to as many as possible and you will get it.
If you see you received a drink from a green named newbie, and it doesn't show on your level up page, it's because that user clicked the "Return Favor" link. They have to come to your page and click the "Send Drink" link. Since they did send something, you can gift them again, with a note asking them to come to your page and click that link so they will count.
Volume Volume Volume, do a lot of these.
Latest update. Since most NooBs don't have a salute photo, you may want to turn that requirement to view your page off, at least until you get this part done.
