From what I've learned, I need to add a plugin, however the free version of WordPress does not allow plugins.
The logical assumption then is that you cannot put ads on a free WordPress blog - correct?
So it's necessary to pay the $99 to upgrade the blog before you can put an ad on it?
If this is so, it seems to be better to stay on Blogger, where adsense is integrated with no fee.
Please tell me if I am misunderstanding. WordPress seems to be the more robust platform and where all serious blogs need to be, but I can't see how to make this work at the moment.
Help is appreciated. Thanks.
