Thank you so much Fiona for the support and the tip!
There is SO much to get stuck in to Hive, I think I'll be writing blogs for the next year! I think you know more than you say you do, I don't know about tipu and this whole !tip thing but I really want to create a comprehensive series focusing on Hive as it's the platform I know best, is open to everyone and you don't need to have any understanding of blockchain technology to get started!
You might want to ask @traciyork to write a post on ! tip. There is also tipucurate... If I remember the technical details a tip means the amount goes direct to the recipient's wallet. And it's the whole amount.
