(Ramamia developer here) We get some negative feedback about not having passwords. So I think the way we're going to approach this is allow people to use their instant login link anytime, so they can bookmark it, keep requesting it from the homepage when they aren't logged in, etc., but also allow them to set a password in the user settings. If they aren't logged in, and set a password, they can log in immediately with their password. If they didn't set a password, or forgot it, they can request an instant login link be sent to their email again. A big portion of the family market are people that aren't insanely knowledgeable about the internet. They can bookmark the instant login link when they're logged out, or they can check their email to get it again. For people on the go, this will allow them to check their site by just logging in even without an instant login link. In fact, the new period that we remember you for is 6 months. As long as you don't clear your cookies, we'll remember you for that long and you won't have to login again. Also, re: usernames, nope - even if there are thousands of Smith family accounts, it doesn't make sense to stuff them into one family.
