LEGO-related questions sometimes appear on Worldbuilding SE. I know this because I have posted them occasionally myself.
I currently have two such questions. I'm wondering if it will be okay to:
(a) Ask a supplementary question here that will get me some extra information
(b) Somehow 'advertise' here that I would like help from this expert community. You might say that this question itself is such an advertisement! There is some truth in this but it is not all the truth.
For those who are interested, I'll post the links but hide them to avoid being too blatant.
I have other LEGO Worldbuilding question going back awhile.
