Webber is an open project, so we expect contributions from everyone that uses or extends the software.
Any kind of collaboration will be welcome, from just references to servers using Webber to (more or less extended) modifications to source code. Specifically, new processors will be included in further Webber releases.
The availability of new contributions and other notices about Webber are distributed through the APP-WEBBER list. From this page, you can subscribe to the list, or browse through its archives.
