Accurate. Very comprehensive, too! We only differentiate between standard (enrolled) shares and sponsored shares with respect to the refund policy. For all other purposes they are treated the same.

rshares are a whole separate deal... you do earn rshares by upvoting posts by @steembasicincome (the rshares value of your upvote * 1.34) but you also earn rshares at a fixed rate based on your SBI units (each unit earns 800M rshares per day)  I was planning to leave rshares out of the FAQ as a more advanced topic, but there has been some call for clarity around them, so it will probably be broken out into a separate question (bonus category!)

Technically management units and temporary units still exist, but our database groups them with bonus units, which is why I am also accepting simplified responses that only have the first two categories.

We are actually trying to move away from 'shares' as an SBI term to prevent our program from being misconstrued as an unlisted security. We originally said 'share' as shorthand for 'share of our voting power', but there has been some confusion around it.

Don't forget you can also earn points by scoring the clarity and helpfulness of other qualifying responses.

Rating 5 for this version - good detail but rshares  is a different topic and "shares" is not the prefered term.
