Post any questions or comments regarding Contest: Show Off Your Skillz in TeX & Friends [TeX.sx birthday] here. I'll add information to the original post if required.
I suggest to change "LaTeX" to "TeX" so it's a catch-all for everything (TeX is the underlying language; LaTeX/plain-tex/Context are macropackages/"formats").
Also, it doesn't make much sense to differentiate between engines (XeTeX, LuaTeX, pdfTeX), but it would make sense to differentiate between formats. Especially since you seem to confuse the meaning when you list LaTeX before XeTeX etc.
Can we have an update once in a while about the current number of submissions? I am really curious already. If so, where would it be posted?
I just found that the character limit is 30000- is this worth mentioning in the original question? Or could it be raised?
Does the submission have to be a document, or is it also OK to post a nice (and I mean really really nice!) macro?
I propose that the question be unlocked. Voting is long over, the current votes don't reflect the result of the contest anyway, but the answerers could still get some appreciation through votes and badges (not rep though as it is CW). It's pretty clear that this question usually wouldn't be allowed on tex.sx, so I don't think we need the lock for that reason.
I still haven't heard anything about the prizes, sorry about that.
Does this mean I can submit as many documents/answers as I want? And also, does it imply there are no categories (like academic paper, cookbook, etc.)?
How about using the submissions for a general showcase of the typesetting capabilities of (La)TeX and its community akin to the TikZ examples on http://texample.net/tikz? Perhaps even on that site.
I'm not sure how I feel about edits to submissions that happened after the deadline. I'm aware they are mostly typo-like corrections, but if we allow these kinds of edits, where do we draw the line? If you submit an application, you can't change typos afterwards, either. Thus, I'm strongly tempted to rollback these edits, just because there had been one week for everybody to fix all flaws, and any left over just belong to the submission.
