I can totally understand that lol. Although I did take my time scoping the place out before I started posting, it is very exciting (and addictive lol)
I sometimes post from my phone but the same way I would from the laptop. I upload my images onto imgur first and use the image URL from there, so on the phone I'm lucky there's an imgur app. Getting the URL has to be done differently I just copped on the extra i. in http://i.imgur.com and the extra .jpg at the end so basically I enter it in manually.
But it can be very frustrating to work from the phone. I'm so glad they made it so mobile friendly from the very beginning.
