@BellaTheCow ur welcome friend!
Yep excited for everyone to join in on the fun 
@skullforceagents work at your comfort my friend.
Basically its to encourage others to donate ink to your series, that you can cash out via paypal. (1600 ink = $1.99 US as seen on Tapas ink shop, but you need to make at least $25 USD to transfer to paypal)
I guess mostly, to kickstart use of that Ink feature on Your Tapas page, say you didn't make over $25 (Ink Feature not mandatory either if you prefer your usual alternate income streams). From my experience it does put readers in the habit donating ink from time to time, possibly stumbling across a past inksgiving post you made etc.
So during inksgiving authors make ink rewards based on total amount of ink collected
eg. 2000 Ink Reward - Q&A with MC
Bob gave 200, Sally gave 1000, Roger gave 1000 ink= 2000 ink reward unlocked!
If you decide to do it, would recommend come up with rewards you feel comfortable making that reflect aspects of your series. Q&A's, Profiles and Top Ten Facts are usual ones and since many participants of inksgiving are creators, maybe stuff like 'their series' shoutouts for top donor etc can serve as incentives too? (can always see other's rewards for examples)
Everyone feel free to add if i missed anything,
Hopefully it isn't too complicated and wishing you good luck
