Editors and Gardeners are LibreCAD users who help maintain the documentation and other information in this wiki.
While lots of folks may have a lot to say about how to use LibreCAD, how the math behind CAD systems works, the design process, etc... Not everybody pays much attention to their grammar or spelling (and the best of us make mistakes at times anyway). LibreCAD is also a very international project, so language mistakes must be taken lightly and corrected in ways that leave the meaning clear to non-native English speakers. This means we need editors.
Editors are grammar freaks; we need them!
Gardeners? Yes, them too!
Most people can think hard about a specific article or the page they are writing, but most people do not think very hard about how the information they are working on fits together properly with other information across the whole wiki. This means we need gardeners!
A gardener's job is a lot like an editor's job, but while wiki editing is focussed on what is on a particular page, wiki gardening focuses on how the pages are arranged — not just to make the information more presentable and better organized, but also to better encourage further editing. An easy to understand wiki is a wiki that is easy and comfortable to contribute to.
Gardeners are Information Architects and Wiki Usability Planners. We need them just as much, if not more, than editors.
