Could someone explain to me what the Thanked & Thanks by your join date & location is about, I see I somehow thanked someone twice although I don't know how.

 

If you look at anyone's post, there's a "thumbs up" icon with THANKS attached in the lower right hand corner. You've clicked on that twice in someone's post.

You've been THANKED 35 times in 24 of your posts. Simple.

 

Thanks
