ROOL set initial goals to make the source code easily available (on the web), and also to establish a wiki, forum and bug tracker. These have been available since December 2006.

Operations exist to facilitate tasks related to ROOL's goals. Additionally, staff undertake development work on the code themselves. Since early 2009, ownership, development and sales of the Acorn C/C++ tools were transferred to RISC OS Open. As an extension to the initial goals, in 2011 ROOL introduced a bounty scheme to encourage further development.

Attendance at RISC OS computer shows is often arranged, with other knowledgeable coders sometimes standing in when ROOL staff are unavailable. A Facebook page and Twitter feed was created in 2012 to communicate events via social media.

Publishing

A number of book titles have been published starting in 2015 with the RISC OS Style Guide, a three book set in support of the Desktop Development Environment, BBC BASIC Reference Manual and the RISC OS 5 User Guide.

Forum

Online discussions take place on the forum. Developers can seek technical assistance with writing software, debugging, and porting the operating system to new hardware. End users can seek assistance with applications, emulation, and enquiries of a more general nature. A common area exists to make announcements that are broadly related to the theme of RISC OS, and discussion of future wish list features or applications.
