Right off the hop here, I make no promises. But I did recently sink some cash into editing softwares, so I might as well get some use out of them.
After seeing a few people have problems, namely language-related, being taught how to do intricate tasks via text in Discord, it seems like a video tutorial series wouldn't go amiss. I'm sure I'll need some tutoring on the proper way to use some features (especially Artist entries) myself. Hosting these on YouTube means they could be subtitled and translated as well.
To begin with, how to edit tags, adjust account settings, and upload (especially via bookmarklet) are the basics. The latter I could use some input in; are there any sites that require special steps as compared to Pixiv that should be highlighted? Things such as using :orig for images on Twitter.
Are there other topics worthy of being covered?
