You can now do this.
The bar for thanking or liking appears BELOW each post.
I would use this on things you really like and not on every single post! In other words don't use it just to be very amiable on *every* single post -- or it loses meaning for the person receiving a 'like' or a 'thanks'. I think this will be a nice way to have valuable forum information highlighted.
You can EITHER 'like' OR 'thank' but you cannot do both on a single post.
You will NOT see the bar below your own posts -- because you cannot thank or like your own posts!
Oh yeah and you can 'like' or 'thank' this post...
