One of the other things I'm trying to do is make the tags consistent. We've never had rules about tagging, so some people do and some people don't and some people tag one way and some people tag another and the oldest posts aren't tagged because they were made prior to the existence of tags. So from now on, here's what'd be good for people to do for tags:

Author names: author: username OR preferred pen name
Artist names: artist: username OR preferred pen name
Art styles: art: icons OR banners OR wallpaper (or other art style we don't have a tag for yet)
Pairing: pairing: rimmer/lister or whosoever it might be. I recognise and bow to the inevitability that we will have both pairing: rimmer/lister and pairing: lister/rimmer as options. You get that. I just want to make it a bit more consistent than those two AND 'lister/rimmer' AND 'l/r' and whatever else.

For crossovers, add fandom: whatever the fandom name is

There are a lot of other things that need to be fiddled with tag-wise, but if we could bear those basic guidelines in mind and I'll work on putting together a full list of tags; at the moment there are a bunch of tags that need playing with to be useful, and a bunch of posts that need tagging, so it's going to take a while. I don't want to be all whipcracky, I just want to make the most of the tag system.

Edit: Following the suggestion from debris_k below, I am turning off new tag adding. If you need to add a new tag to your entry (e.g. an author tag if you don't have one already, a character tag for a character who's not listed, and so on), please tag your post with tag request and put the tags you're requesting at the bottom of your post, and I will create the tags for you.
