^ That right here

Just wanted to send another shout out to ostybirb. It is a Multi-site Uploading feature for PC. You can upload one of your arts to a BUTT TON of places at the same time instead of sitting around uploading that same art for 2 hours on 8+ platforms reformatting and coding your descriptions.

• handles a increasingly larger amount of Art SItes like DeviantArt, FurAffinity, Twitter, Tumblr, Newgrounds, pixiv, and even handles some more not as well known places like Pillowfort, and can even upload to Kofi or your discord. (as of me writing this, it works with 26 art sites)

• *does not work with mobile-centric app sites like Instagram and Amino. just so ya know.

• Schedule posts. ffff yes

• Formats code appropriately for each site if you do link, colored text, etc in your descriptions

like, even if you just post to 2 platforms, its still super helpful. If you are always "ug, I wanna post to this place, but I always forget" try using this. It's def made me visit my other platforms more often since I am not using all my time uploading while on it. I can use that time to browse and comment. I've even ended up liking visiting my newgrounds and weasyl. I'm posting stuff on places I'd normally never because too much work like FurryNetwork and Pillowfort. It's given me free time to maintain my mobile platforms I reside like my Furry Amino.
