Yep, but which package consist need classes? I ask it at first post. Wow, I found JSON package at smalltalkhub.com. I first load JSON package from smalltalkhub.com and postmark package successfully loaded. Good, thank you. I resume my notes: 1. Wrong reference to external site with example of usage postmark http://articles.tulipemoutarde.be/send-email-from-pharo-with-postmark - incorrect http://tulipemoutarde.be/2011/12/29/send-email-from-pharo-with-postmark.html - correct 2. At smalltalkhub.com exists two projects a. PharoExtras/Postmark - correct project with packages b. PharoExtras/postmark - emp[ty project without packages I understand that you have little time, can I do something to help fix it?
