(Apologies for the brevity of this - am at work at the moment.)
I really, really like the concept behind this, but with the way it’s currently worded I foresee it causing a few problems down the line:
1. Allowing stub articles doesn’t eliminate the work needed to make them full-blown articles - it just pushes the work further down the line, where it’ll likely get ignored/procrastinated/etc. for eternity.
2. Bad actors - which past experience has demonstrated some newbies to be, unfortunately (i.e. Edto, Rascaldees, etc.) - could easily abuse this to sneak in ludicrously OP factions, tech, species, etc.
3. In my personal opinion, fleshed-out articles are of VASTLY greater utility to GMs then stub articles, because it gives them more to work with - especially when it comes to opfor characters (such as big bads), units, locations, etc. Fleshed-out articles don’t have to be technical manuals, either - they just have to have a bit more then a couple of lines of text.
