Can we use the Ad Network on blogs? I'm sure I saw a coment by someone that they are using it on a blog. I thought it was just for Forums, or site-wide on HTML sites.
Yes, yes you can use the ad network on blogs and almost any other websites, there are detailed instructions on the setup available once you sign up.
I've looked through the FAQ, and it mentions blogs, but it seems as though it is intended for blogs which are hosted on your own site, whilst my blog is hosted at Blogger.com Is it possible to use the Ad Network on Blogger blogs, or can I only use it if I host the blog on my own site where I have access to the .htaccess file, and can place a txt file and php file?
There are so many great offers on domains and webhosting, so should be able to get a domain and some webspace for a few dollars a month. It is always a good idea to own your own domain.
