It is not necessary but you can. You just edit and change one of the hashtags 2nd to 5th to #curie. If you don't do that for this post, you can do it for subsequent posts. When i am home, i will just submit your link or you can go to steemit.chat and look for #curie channel and submit your link! Inform them that you just heard of them, so you decided to leave your post with them!
