About limiting post viewing

Hi everyone,

I am considering a feature that allowed free user to view only the title/summary of a post in a certain category(like the vip cateogry), but not able to click on the post to read the full content.

Or a free user can only read few post in restricted category per day.

And they should be able to creat new topics in these restricted category, and check their own topics. Even though they are restricted from reading other articles in the same category. (My idea is free user need to contribute content to the community, get rewards and then redeem their vip and get full acess.)

Does anyone know if there are components I can use? I am really not fammilar with ember.js and Rails…

Thank you very much!!!
