Here I am, crashing through the ceiling on your all for the first time in 6 months! :)
This special occurrence to let you know that Wikia are making updates! The change to our version of MediaWiki software will come with support for solely HTML5 being available on TESWiki.
As we speak, Veetor-Bot III is rolling through pages containing outdated html tags and updating them with the necessary changes. This means that you, good community members, won't have to do anything to pages yourselves. If you have custom signatures, though, you'll have to head to Special:Preferences and make sure you've not used any of the tags that HTML5 does not support.
Thanks for staying dedicated, and good luck with updating your signatures while I slave away updating all the other deprecated tags. :P
I'll see you in January!
