If you have a static site, you are limited to using someone else's counter. There is no way to run PHP code from a static site. Also, even if you were to use JavaScript, there is no way for your static site to store that data. So, still not an option.

The only real solution with such a site is to use someone else's counter as you mention in #2.

Not all I2P users have a clearnet outproxy configured. So, using a clearnet service is not the best option. Possible privacy issues aside.

I have a counter on the front of my notbob page. If you mouse over the van on the upper left side you will see a little box with a green graph. While it does not currently show the count, it still counts.

It would not be hard to write a multi-user count. I could likely code one up that would work for anyone pretty quickly. Something basic that just displays a number.

You would embed it into the html code with <img src="http://countersite.i2p/cgi-bin/counter.cgi?site=324832483">

Note the random number. There would be no need for me to even know what site it's counting for.

And, that would all you would have to do on your end. That is if you just want a count. If you want graphs and more complex breakdowns, that's another story.

But, a simple one would be easy. And, as for privacy, so long as you trust the person who's counter you are using, then you are good.

Feel free to hit me up on IRC if you want to discuss this further.

As for discussion, this is a good place to do it.
