Wiki - global
I would like to be able to have global Wikis. I use the Wiki to create training documents for staff. These entries would be useful to have across all projects. Perhaps the ability to have Wiki entries appear in multiple projects without having to copy them over?
You can create a project called Wiki and store all cross-project Wikis in it. Use tags and wiki lists to separate. That project can have only a Wiki application installed.
If you use a Business or Enterprise plan create a template project with one wiki pointing to that project I mentioned above. Call this wiki README or START HERE and it will provide a pointer in each project to cross-project Wiki section.
