I dare to claim that US and non-US members would benefit equally from a private section. Release dates, IMO, are the least relevant on the list. It's very easy to refresh the MAC website to check whether a collection is online or not. At least, that is what I do.I'm sad to see the fees are that high, it's too expensive for me and being a non US member I don't think I can benefit a lot from it. I hope the collection info and swatches will still be shared in the regular section, I'd be sad to see less activity in the regular forums from now on.
I hope it's a good solution for those who share release dates and launch information, without having to worry about the evilbayers lurking.
The benefit of a private section would be the access to swatches, collection names, color stories, and the discussion of all the above including what works for what complexion. This is the real issue - privileged information that is shared in a premium section - at stake.
Further, the conversion from Euro/Dollar is in your favor, thus technically, you are paying less that US members. However, I certainly do understand that some are reluctant to pay a fee. It is money after all, but if it benefits our online community, it is money well spent.
