A lot of artists I follow advertise through journals, it's a way of getting a message out that's more text based than just an image that's announcing something

I mostly buy comissions form here, so feel free to use journals to post ads about comissions

I feel like it's probably better to use Journals for comissions. If you post something as a drawing it will get lost in the sea of other uploads, and if someone is Watching you but doesn't check their new arts they won't see it. It's a lot easier for someone that's Watching you to see a Journal
