I have changed the layout of my website, now there is much of space available where i can put some banner ads etc...My website's PR is 4. I have decided earlier that i would never offer advertisement on my website from any of other website, but someone told me that it is helpful, it increases the reputation of website (having that much of advertisers). At the moment i'm offering free advertisement on my website (see my signature) for the days ranging from few week to few months (depend upon the niche).
The site is obviously about 't shirts'? I sorta worked that out by going through all the links. Just wondering why you don't explain what the site is for/about on the homepage. You must be doing something right to get pr4 though.
