I looked deeper into the My Profile . which is used in those styles/themes I listed earlier..
User CP is used in the other styles.

If you click Edit Options - that will give you things you can change messages, PMs, notifications..and such..
https://www.neurotalk.org/profile.php?do=editoptions

Or you can sample the the other themes with the drop down near bottom of pages, usually on the left side..
pick one and it should change until you change it or log out and if you like a different one to use all the time you can set it in the edit options sections..
Safari might display things a bit differently but shouldn't be too different..

Just to add re the Theme/Skin changes in the drop down box bottom left of all pages......it's best done from the main forum index page https://www.neurotalk.org/ as sometimes it doesn't "stick" when done from another page

It appears I am getting along a bit better. I have checked Tulip, Spring and currently using Sand.......
Appreciate the help and info....
