how do I RENT my Trendwest timeshare credits??

I joined the membership and am disappointed / confused that now I have to pay additionally for each posting that I would want to post.

With Trendwest / Worldmark the credits can be booked anytime, at any of their resorts, and often transferred as well.

Will you share with me your tips for successfully posting your timeshare credits / points? Thanks! Michelle

I am a WorldMark owner. WorldMark has an owners site that you can post your rental of credits. I bought 20,000 credits last year.j Marge
