Nope - just enter it. If you can make a poster in Canva do that. If not, steal the main one by right clicking and Saving it.
Then do your post and link it. Once you do that, let me know and I will take a look for you.
The idea of this is that anything goes for the purpose of you getting a post out and learning steem :)
I think I have pulled off posting it on my blog and providing a link to it in the freewrite contest. Let me know what you think. And thanks!!!
