<div class="mw-heading mw-heading3"><h3 id="Publishing">Publishing</h3></div>
<p>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.
</p>
<div class="mw-heading mw-heading3"><h3 id="Forum">Forum</h3></div>
<p>Online discussions take place on the forum. Developers can seek technical assistance with writing software, debugging, and <a href="Porting" title="Porting">porting</a> the operating system to new hardware. End users can seek assistance with applications, <a href="Emulator" title="Emulator">emulation</a>, 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 <a href="Wish_list" title="Wish list">wish list</a> features or applications.
