Hi Alan... I know all about the shaky body, as I need assistance standing up, and walk and move spastic like, head, body, arms, legs, not quite what we figured would be in our plans for retirement. It is very tiring to say the least, on the whole family, yet we have adjusted... Just what things are... Undo is my best friend lol. I have windows settings for large text, via settings, ease of access, display. Also you always have the magnifying option within the app it's self. As for not getting into a membership site, some cookies are your friends, and passwords are important to write down? Stay strong, cheers
