LOL! Well, whatever it is, I just want to point out that we had 'em before the secular world came up with medications for ED. Just sayin'.
I don't know much, but the little I know is about the Dominicans, and things can be sort of extrapolated. When Dominic came along there were already a few established "rules" for "religious." Here Rules does not mean, necessarily minutely detailed instructions for common life (or for solitary life) but more programmatic, even "style" issues.
Dominic wanted a group of priests who were trained and devoted to evangelism and who led lives as simple and unadorned as the Albigensians. He was told he had to use an existing rule as the basis of his new rule, so he modelled the order on the rule for Augustinian canons (where I THINK "canons" means not laws, but people living under specific laws, something like that.)
Before the "first order" the "friars preachers" (friars means brothers) got off the ground, he established a cloistered nunnery for young women who had left the Albigensians but wanted a place to live and to pray. Their specific mission was to pray for the success of the preachers.
THEN the first order gets founded. Then the "Third order" which is VERY fluid in structure. These days usually it's women who teach or minister to the sick or whatever. They have to get permission from the first order to call themselves Dominican. Presumable they WANT to be able to call themselves that because they feel some kind of kinship or alignment with an evangelical mission, and they like the flexibility of the Dominican approach to things.
But at the same time as Dominic (late 1100's -- early 1200's) there were groups of lay people who led lives with a commitment to a "rule" of prayer, study, and evangelical stuff (in the broadest possible sense, I'd guess.) These groups tended to cluster around Franciscans or Dominicans and finally made the associations formal.
All this is to give an example. I'm a Dominican. But I'm a lay Dominican. So I am, as it were, brother to a BUNCH of people around the world, all doing very different things, but all with a commitment to prayer, study, evangelism, and community with one another. That's ONE sort of 'meta-family'. All the Franciscan groups would make another, as would Benedictines, Carmelites, etc.
And I guess the last thing to say is that all these are approved ways of being Catholic. We find that what helps us live into the Gospel is this kind of thing. We don't think the Carmelites are doing it wrong or that the Trappists are better than we. They have their call, mission, and gifts, and we have ours. All to the Glory of God and the building up of His Church, we hope.
I hope this verbosity is helpful.
I'm sure there is a patron saint of ED somewhere among the 10,000. :O)

Why should there be any groups with differing orders, rules and regulations? If you were to transgress the orders rules, wouldn't they kick you out?
