I like how easy it was to create an account as well as upload my photo or logo design from Photoshop/Illustrator etc..
It's not really anything negative about this software! Sometimes when you're using other programs such as Illustrate /Photoshop (etc.) if something happens while uploading say another program crashes then once again everything gets messed up so be sure have multiple backups available during these times!! This helps prevent any data loss issues which could occur otherwise because we use Dropbox almost 100% daily throughout our day jobs & personal lives :).
