I check the Gifts section once in a while, but that doesn't show tips. I've never seen that I've gotten any tips. They should really have that as Sitemail, or at least a notification. I feel like radioactive pond scum for not thanking you for the first tip - I had no idea!

Come to think of it, I hope I didn't miss anyone else's gifts too (So sorry, and THANK YOU! if I did)...
