I don't have a scale and I am not able to put pictures up because the only computer I have access to is the computer at my work and I share it with my other coworkers. So I don't always have computer access.
Digital Scale is cheap, cheap at Walmart, I paid $10 for one I think. As for the computer part.. it's a bit more annoying and a bit of a hassle at times, but you can totally do it all using your phone as well. Just use the forum on your phone's web browser.
I think some of our members use Tapatalk, but I have no experience with it myself.
