[wrong topic section - sorry. Absent-minded error, but I don't know how to delete it or move it.]
I am using a lightly-customized version of Cutline 3 column split on multiple domains. All domains are on the same webserver. In some the posts on the front page appear in a font that is much smaller than the standard (sidebar text is not affected). In a few the posts are in a too large font. I am uploaded the exact same custom template files to each site. Examples: 4u2click.com (small) and aboutsales.info (huge). (Note that both blogs are still under development.)
