Should the traveller wiki implement a "Fanon" Tab, thus forcing almost 100% of my sector development in the Vargr Extents to this second-class existence, what will happen is an unbalanced state where the article tab will read the most basic, boring, minimal, official information on the article topic and displacing the creativity of the contributor to the Damnation Tab and branding their creativity as ignorable, unworthy, too lame to read, beneath your notice.
I don't grok your complaint. Seriously. There is no second-class existence of information.
There is canon and non-canon.
I use both interchangeably without concern. But if it's going to be a wiki; shouldn't it be accurate? I love the work you did on the Extants but why is labeling it as non-canon delegitimizing it? It's already illegitimate (ie. fanon).
A non-canon tab would do wonders for expansion, creative input, and different interpretations of 3I and beyond.
A place to put multiple versions of a planet/system/polity etc. Right now, three contributors to a system (with vastly different interp/viewpoints) only muddle their vision because all of their information goes on the same page and is in-line with the other information. The first person to post non-canon info to a wiki should not control its content.
Claiming that it would water down contributions or be disrespectful to people who did cool things with setting material but, quite honestly, weren't asked to do so is pointless. Canon is Miller. Anything else should either be posted and labeled as such (fanon) or not published at all.
Since not publishing is the death of creativity, why would anyone care if their custom content is identified as such? That's what it is. Period. Anyone who thinks otherwise is feeling a sense of ownership based on "first-in" that is simply not accurate. Furthermore, how the heck can we give credit to people like you if we don't know it comes from personal interest and investment of personal time rather than actual books?
Again, COTI, I beg of you... be inclusive, not exclusive. It is the fundamental fail of these boards. A "fanon" tab would allow everyone/anyone to add ideas to the setting without upsetting anyone who insists on canon.
