It's more of a layout issue, really. Add article is in an odd place - I'd expect it to be on the right side infobox, or maybe above the articles. If I didn't know from earlier experimentation how it worked, I would never post articles.
Another issue, in the same vein, is that in the magazines articles are under 'Threads,' but they're called articles. There's pretty much nothing associating "Add new article" to 'Threads'. Again, something that you'll have to just try out.
Other topic altogether. Why is there an empty space at the beginning of edit area?
I actually tried to go to /m/kbin, and since it wasn't there, I created it. Can I redirect it somehow, or should I add moderators from the dev team (you, for example)?
There was a lot in there that was new to me, too. The greatest surprise was the connection with sight; I'm overly sensitive to bright light, and have trouble with blue light (nighttime neon signs are horrible). There was a lot I recognized in myself in this.
