@dzhuang ping :)

[dzhuang]

See discussion in #621. I think what you want is a bonus page?

[inducer]

I think what you want is a bonus page?

Yeah, pretty much. Do we have a dfiferent mechanism for those? Because optional + has value makes a lot of sense to me to express that.

[dzhuang]

I agree. So there are some agreements need to be reached to achieve that:

1. Warning that there're bonus page unanswered (for pages that have non-zero values), when a user is finishing a flow with bonus pages.
2. Display bonus points in those pages
3. Any more?

[inducer]

Warning that there're bonus page unanswered (for pages that have non-zero values), when a user is finishing a flow with bonus pages.

Only if they carry points.

Display bonus points in those pages

Could simply be shown as "5 points (optional)".

We may want a separate grade sum for "bonus points" on the results page--maybe.

[dzhuang]

That sounds reasonable, but I have no time to do that in a while. Maybe I can help in testing if you can submit a patch.

[inducer]

The earliest time where I envision I'll have some time to hack Relate is around Christmas. I'm teaching a big, Relate-heavy course in the spring, so I have some motivation.

[dzhuang]

So I'll wait for your ping :)
