okay... i figured out #1: I was using category blog on the menu and needed to go to the menu item and check off "no" on "show page title" under the system parameters.
#2) -- still confused and have added a similar question -- changing the font-size for h2 in the css doesn't appear to have any effect. I wanted to make that larger, but don't seem to be able to? or am i editing the wrong header -- from what i could read of the css it looks like the header with the titlebar icon would be h2....
what's really weird is i have the same css on my localhost as the online version and yet the localhost has a much larger font for the same headings on the page...
why??? and why can't I seem to adjust it???
sorry for the newbie questions...
