“I was Running Opera on a nephew’s system, specifically ver 7.03 US – the adware version. I didn’t mind ignoring the ads too much, and even occasionally clicked on a few to feed the clikthru hungry bannerati.

I like those folks, and have recommended it to so many.” Read the article at The Inquirer.
