Hi Richard I did not see your original post because I messed up with my account. But thanks for your email :) Now the cool stuff if that we can also read the books from within Pharo. We should improve the Microdown renderer and suddenly we will get shiny cool documentation.

by Giovanni Corriga March 19, 2024

March 19, 2024

In this presentation, Maximiliano Tabacman will be presenting the main features, abstractions and design decisions behind ERA, the Electronic Roleplaying Assistant ( https://preview.drivethrurpg.com/en/product/137825/ERA-for-Rolemaster ). ERA is currently being used to create characters and manage the adventures of many gaming groups across the world, supporting Navigator RPG, Against the Darkmaster, Rolemaster Classic, Rolemaster Fantasy and Rolemaster Unified. We will review how Pharo allows creating a deployed version that runs locally in Linux, Mac and Windows, while Digital Ocean and Auth0 allow running an online server with different user roles. https://pharo.org/success/RolPlayingAssistant.html We will also mention how ERA makes use of the different frameworks developed and maintained by the Buenos Aires Smalltalk group, hosted at Github. Maximiliano Tabacman ( https://www.linkedin.com/in/maximiliano-tabacman-9aa4b817b/ ) is a long time Smalltalker with a Phd from the University of Buenos Aires. He is a Software architect at Mercap, executive secretary at FAST and creator of ERA. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/299364517/ ) to receive the meeting details. Donât forget to bring your laptop and drinks!

Consequently, the reviewing process will be organized in two rounds: * in the first round, all submissions will be reviewed by at least 3 reviewers. Based on these reviews authors will receive a notification with reviewers comments, advises, and requirements and papers that are not rejected will be invited to be resubmitted in an improved form together with change log and answrers to the reviewers. * in the second round, PC chairs in collaboration with the reviewers where needed and possible, will evaluate the improved paper version and notifiy authors about final decision on acceptance/rejection.
