For those posting, we all know each other, presumably, and so whatever posting guidelines there are are unspoken. I would like to make sure, however, that people us the marvelous lj-cut function in the case of NSFW art- art you wouldn't want your boss seeing on your computer at work. By writing <lj-cut> before a chunk of text and </lj-cut> after it, it collapses that portion of your entry to a link that people can then click on it to expand the entry.
Oh, and here's how to upload images if you don't know how to- BAM- so yeah. Enough for now? I think so.
Happy posting and reading,
