Gringotts Update:
The first batch of S-PT deposit bonuses have been paid.

I've decided to end the Gringotts deposit bonus scheme in 4 days from this post.

Any left over S-PT will be used for other bonuses and bounties that help CK & Gringotts grow and prosper.

The deposit bonuses will have run for ~30 days, and the remaining S-PT can probably be put to better use in other ways.
