I read a post (from 2012) recently in the Linguistics meta that "...The users that committed cannot talk about them in existing sites at the moment....".
Before that, I had been going to consider a question about ConLangs in the Worldbuilding S.E., but now having read that, I'm reticent to bring up the subject there. The key concern in this case being that it would be an overlap of a proposal into a beta, which might be unacceptable or contrary to an explicit rule.
Given that, my question is: to what extent is it acceptable (if at all) to point people in one S.E./S.O. (particularly if they're full or beta) to another one (particularly if the pointed-to site is a proposal)? How do you feel when you see an answer like that?
I ask because I don't wish to cross any etiquette lines, and thought that asking from within the Area 51 board would perhaps be less contentious than were I to go directly to asking on someone else's meta.
Note: I'm not sure that this fits perfectly with the tags of "Science" or "Culture", but linguistics and languages are in the S.E. list under those headings (respectively), and I thought that they were likely relevant.
