New design not better
 

I recently started using Fuelly. One of the nice features is to be able to access my specific car link directly and share it with others. The new design made it mandatory to sign in to see the page. This is not doing any good for the experience. This is specially annoying when one gets summary a after an SMS update. The summary just gives a link to main site.

What link are you specifically referring to?
The vehicle profile page? All links should be accessible with our without logging in.

If you're referring to why your Sienna wasn't easily found from the Browse All Vehicles page, that's because before today you didn't reach the 3-fuel up threshold that Fuelly requires before it's publicly visible there. However, you could've click the [show all] link at the top of the car category and you would've seen your vehicle listed then.

Again, please let me know which link(s) you were wanting to share so we can double check for you.

Below is sample of current SMS reply I get:
Fuel-up Added! MPG: 16.1 , AVG MPG: 16.2 More stats on Fuelly: https://www.fuelly.com

Below is old SMS reply I used to get:
Fuel-up Added! MPG: 15.4, AVG MPG: 16.3. More stats on Fuelly: https://fuelly.com/261959
Note the link in the old SMS message.
The link used to work without logging and take one directly to vehicle profile page. Now it is not sent with SMS and when I tried to use the old link without login I was redirected to login first.

I'll pass this along to see about getting that URL fixed.
However, the old link doesn't prompt me for a login. It takes me directly to your Sienna.
