Although i'm a newbie but i understand the resteem/reblog very well, it's similar to Twitter "retweet". I also noticed one can not resteem posts older than seven days nor save them without copying the link 💀💀. I stumble on some olds post here and sometimes feel like sharing with other newbies but the resteem option is not available. Some days back i also discovered @resteemable have provider a platform where one can actually make them resteem your post. All you need do is copy your post URL, delete http// and replace it with " re" and BOOOOOOOOM your post gets an instant resteem from them and maybe an upvote. Thanks for this post @eurogee ✌✌. Steemit to the world.
