Very nicely done and I've been looking for something like that for a long time! Couple of immediate remarks: 1. Allow sign-in using e-mail in addition to user name. I am using firtsnamelastname or FLastname or sometimes something else (depending on availability) and need to remember each time my username. Remembering e-mail address is much easier 2. Unless you want to limit your addressable market to US, Liberia and Myanmar, add a possibility to specify my height and width in metric units (cms and kgs)
