general.tax.pricesinctax - this
determines whether the prices for items you enter in the back end
are inclusive of tax or not. In the US, prices would typically be
entered exclusive of tax, and this setting would be 'n'. In Europe,
it is more common that prices would be inclusive of tax (though
business-to-business oriented sites may use ex-tax
pricing).
frontend.users.access - this provides control
over the level of access to the site that the public
has. 'No' = full site viewable 'Yes' = must login
to view site 'Partial' = prices & add buttons
hidden until login 'Browse' = full site viewable, must
login to
checkout
frontend.display.images.large.linktype
- this determines whether large views of images are launched in a
new browser window [n] or within an ajax popup [a]. The latter is
generally preferred these days as it's virtually instant and also
avoids some of the issues with popup blockers that may interfer with
launching new windows depending on browser
settings.
