In all the years I've been using this site, I've always thought the help:cheatsheet was awful... Sorry. I feel where the help:cheatsheet failed me is in that it isn't short and concise. It's just a long list.
I figured I'd try to do something about it... so I've spent the last couple of hours writing up some stuff.
I'm far from done but I'll take a break now and continue it later in the near eternity.
Here's a run-down of what I have so far:
help:search
A page meant to show how search works on the site. It should show the most used search functionality while being kept as short as possible; linking to related Wiki pages for more detailed info. For instance, the Sorting portion should not list every single sort option as most are probably less frequently used. Instead it should link to a separate Wiki with all sort options listed, regardless of frequency of use.
help:imagesize
A collection of all tags and metatags related to resolution and filesize.
help:number_syntax
A page explaining how the number syntax (aka the id syntax) works.
help:metatags
A cheatsheet like page for metatags but with more descriptions and examples. Not yet started.
help:sortings
A cheatsheet like page for sortings but with more descriptions and examples. Not yet started.
help:autotags
A list of all tags that may be automatically added to posts.
Feel free to come with comments, suggestions and critique. Or hey, if you feel like it, delete everything. I won't be offended.
