I'm not sure if the forum already have this or similar feature and if somebody recomended the same.
I would like to mark posts and put them in my "Collection" for easy access in the future. From this "Collection", I can also create "Topics" to separate different topics, in case I marked too many posts :)
Sometimes I hit a problem which I remember seeing a post in the forum similar to my problem or the same but have problem looking for it. Also, sometimes I see an interesting topic which I like to save somewhere for future reference.
