Interesting, I never knew you had to be a member for at least a year, or have at least 500 posts, or a BN Plus membership in order to post on the marketplace. All I recall was leaving for a year, coming back when I was in an apartment of my own, making a few forum posts and the marketplace was just "there".
Guinea, I don't know if you can take this information in or not, but when I first came to Basenotes I came here from a previous forum directed more towards men's shaving and skincare and such. When I came here at 18 from that forum, the fact that I could be part of such a vast database on fragrances (a then-blooming hobby for me), I didn't know what to do. Coming here from Youtube isn't so much of a big jump, except in terms of format - instead of talking about fragrances to the camera for the world to see, this is an old-fashioned forum.
Now, while you may not get the thousands of video views or subscriptions on Basenotes, you will get noticed. If you're curious about fragrances and want to know all you can about the fragrances you love, or want to try, or just fragrances in popular, you will find the answers here. The niche and designer world is A LOT more vast than I assumed when I first came here, and trying new fragrances and even announcing your Scent of the Day is all part of the fun - it may even extend onto your Facebook! Youtube reviews are nice and all, but there are certain ways to polish your assessments of fragrances just by reading text reviews, e.g. Foetidus and Off-Scenter.
It's an internet forum, dude. If you can rough it out, keep your cool and get to know everyone, next thing you know you'll be able to utilize the marketplace if you really want a certain fragrance.
