Yes, I'm sure we're both very thankful that I used an edit summary. It helped you to immediately know the intentions of my edit, and avoid confusion.
Let's see your edit summary when you re-added the wiki:
Oh, there isn't one. Perhaps if you had used an edit summary such as "The footer has now been added to this wiki", there would have less chance of that wiki being mistakenly re-removed.
I've always used edit summaries when editing the footer: http://community.wikia.com/wiki/Template:Wikia_Gaming_Footer?action=history
Even today: http://community.wikia.com/wiki/Template:Wikia_Gaming_Footer/List_of_Wikis?diff=951815&oldid=944063
You still didn't use an edit summary for some reason, despite the fact that you already acknowledged that I used an edit summary with my edit.
Apparently you don't often use them:
I can't even tell what you've done in each of these changes. ("Added gaming footer" would have been really helpful - I found when you added it, October 9th 2012, so don't act as if the footer has been there all along.)
I see that you are aware that edit summaries exist:
But scrolling down that page, I see that it's more common for you not to use them.
No time like the present to become a better wiki contributor and start using edit summaries more often!
If you're forgetful, there's even a preference "Prompt me if I leave a blank edit summary" to help remind you.
Although there are many times when an edit summary is redundant - on talk pages I usually just use "reply" as the edit summary, unless my reply can be summarised easily, such as "Yes", "No", or "Good idea!" - there's usually some of useless summary for most edits, especially in the main namespace: "fixed spelling", "fixed link", "removing redundant information", "major overhaul" - the list is practically endless with ways to describe an edit in a helpful way.
You may like to read this page about edit summaries, which provides some great tips: http://en.wikipedia.org/wiki/Help:Edit_summary (I'm linking to a wikipedia page because it has good advice and examples, not because I'm trying to say "wikipedia does it this way, therefore wikia does it this way")
I contacted the wiki: http://halo.wikia.com/wiki/Special:Contributions/452
No reply was ever posted: http://halo.wikia.com/wiki/Talk:Main_Page/Archive_16#Wikia_Gaming_Footer
Admins are not "the wiki", therefore it is not required that communication with "the wiki" be done via admins specifically. I contacted "the wiki" regarding content on the main page via a message on the associated talk page. No reply was given from anyone on the wiki, including admins, therefore the message was ignored by all users, including the admins.
Last time I checked - which was seconds ago - "following" a page follows both that page and the associated talk page, so all users following the main page would have been been notified of the talk page message - either by email or by Special:Watchlist - admins in particular should be following the main page for changes, and so a talk page message on that page should get the attention of any admins.
Additionally, there's a message at the top of Talk:Main_Page
- "Note: This page is Halo Nation's community center. It's a place to ask questions and propose projects."
So the main talk page is clearly a monitored page where that message should have been seen.
Incidentally, that talk page archive was created via copy/paste (Wow.) on Oct 22, 2012, http://halo.wikia.com/wiki/Talk:Main_Page/Archive_16?action=history
So at the time you added the footer, my talk page message was still on the "current" talk page - yet you didn't reply to it, although the admin who archived a page containing an un-addressed message is more at fault, obviously.
