Re: Changing Members theme
I think one of the reasons there is a separate Member’s theme folder/CSS is because it is such a unique thing (ie. it’s not typical WordPress), whereas the blogs and site itself can use any old theme (with some exceptions).
The only thing that you really have to pay attention to is how you display the three columns that the member’s section is displayed in by default. By simply editing those widths, how they “float”, and other basic CSS attributes, you can easily change how they fit within the page and you can easily match your blog theme.
Hope that helps…
