Site title

Hi there,

i wonder if any one could help me with my little problem with titles…

i’m trying to give my website proper titles, eg.

home “my website”
single post “single post name”
category template “category name”
tag template ” tag name”

i’ve tried everything i can think of, but no joy

PLEASE some one help me sort this out.
thanks in advance!

btw i’m using a slightly modified sampression theme
