I think you just click on someone else's to get to the site. Also I think there is a tutorial on how to do it. Go to tutorials on the blue bar at the top of the minimins screen.

Go to Trying To Conceive Ticker and choose a weight loss ticker, put in all your info and a password and choose which one you want picture wise --- when it comes to the end there will be a code in a box. Copy that code and copy it into your signature on here (in the quick links at the top of the page).
