Hey man, great suggestions!

You can already add your rider location - if you click on "my account", then "Profile" (to the right of your username on the account page), you can input your city, country, etc.

At the moment, I don't do much with this info - but in future, for sure it will be used for others to find riders in their area! Also to display hills in your area automatically, etc. This is a feature on the todo list.

The shop locations will be an interesting one and requires a bit more work - it's also on the list, just a bit further down... ;)

The compiled KMZ files is also something I definitely want. I'm still thinking about the best way to do this, as there are a number of different approaches... and yes, this suggestion is very important - I ideally want people to use the "Find hills" links, narrow down the list, then have a "download these search results as KMZ" link which dynamically generates the KML for all hills on the search results. As you can imagine, that's quite a bit of programming to get right. I will have to take a closer look when I get time.

As for slide hills, could you be more specific? We don't have a "hill type choice list", unless I'm just misunderstanding you?

Thanks again for the feedback.

Not yet, but it's coming soon!
