Move away from so many screenshots that become obsolete so quickly

[cansavvy]

For maintenance purposes, we will want to cut down on how many screenshots we have of other people's websites. Although screenshots are nice for instructing people on how to get set up its a lot to maintain and not for a lot of pay off. I think a lot of places we can substitute for links that describe how to get set up or just generally telling follks to create an account following the websites' instructions.

Things like Google and etc purposely make account creation straightforward so that this is not a burden to new users. We should try to depend on their work instead of making so many screenshots that will be outdated quickly.
