jane_says - yeah, I’ve always kinda leaned towards some sort of co-op living myself. It’s very, very difficult to do in this society, unfortunately. We do idly discuss the idea with various members of our extended family (for us, that includes several dear friends whom we consider family, even though they are neither related to any of us nor involved with us as ‘intimates’). I think we may even manage it one day.
I don’t entirely understand your reticence about the kids, myself. One of my reasons for thinking that a group marriage would be ideal is the possibility of having a whole herd of kids while relieving many of the burdens that modern culture puts on parents. Since (in my picture) the kids would all grow up thinking of each other as siblings, regardless of the specific genetic relationship, there wouldn’t be a problem with ‘finding out’ anything at a (too) late date. But there ya go - mileage varies, eh?
But I hope you do get to be TOBLWGOTCWLDTRAP someday. 
Mekhazzio - exactly! Thank you! It does seem to be easier for some than others - whether that’s due to innate tendencies, rearing, or what, I don’t know. I’ve rarely had problems with jealousy, myself, but one of my partners has had some difficulties. Nothing that we can’t deal with - it’s usually just a signal that we’ve gotten too caught up in mundane details and lost communications temporarily. 
Testy - ah, I thought that might be it, just wanted to be sure. S back atcha!
I’ve no objection to answering questions about poly in general (although I make no claims to ‘expert status’), nor about my personal relationship as long as you’re reasonably polite.
If I think they’re too personal, I just won’t answer.
But I’m not easily offended at any rate, so ask away. You’re right though, this thread may not be the appropriate place. Maybe we should take it to MPSIMS? Or we could resurrect this thread (which for a time became the honorary Ask About Poly thread) - I’m sure Cheffie wouldn’t mind. 
At any rate, I rather like your OP phrasing - and that is, indeed, what RoboDude says he had in mind.
Ptahlis - can you be more specific in your statement? Maybe pick one area of law to discuss? Obviously, laws would have to be reworked, but I don’t think that’s necessarily a bad thing, myself.
I think part of the solution could lie in simply getting government out of the marriage business rather than rewriting laws to work around poly.
Oh, yes, and before I forget - Daniel, I never thought I would type this, but LOL! “Assume” all you want - so far, you failed to get a single thing right, not even the modicum of information that you could fairly easily have inferred from my posts in this thread. Evidently your reading comprehension skills are on par with your manners.
Since your pretend version of my personal situation bears absolutely no resemblance to my ACTUAL personal situation, I shan’t be taking your tax advice, thanks. You’re right - if that were my situation, I could claim those people as dependents. In fact, in one of my previous jobs, I saw tax forms where men had done exactly that - claimed both wife+children and ‘mistress’+children - perfectly legal. (I have no idea of the actual relationship between the two families; I just had to check the tax forms.) However, as I stated, I have checked on my tax situation and I’m just pretty much screwed, thank you very much. Amazing as it may be to you, I am actually more competent to judge my tax liability and options than you are, especially considering that you haven’t the foggiest clue as to my living arrangements.
Oh, and I’m still waiting for your evidence. Making passing references to things other people may or may not have said doesn’t cut it. Neither does mentioning a couple of instances of an outdated practice of a small fraction of a particular religious group.
Without that evidence, I can only suppose that you are, as usual, merely talking out of your ass due to your complete lack of any actual information. You seem to make a habit of that.
I tell you three times: Put up or shut up.
