That's fine, I wasn't aware that it was four copies vecause there was only 1 i could see on my blog. But now I see under posts what you mean.
It's a shame you can't share with different communities. Especially when the commumities you (I) follow basically have the same goal...good content. But oh well, I won't do it again
There is a cross posting feature available on PeakD but even this practise is controversial to many (including me) as that´s basically earning multiple rewards with one post... But again, this post is great and I hope you will be creating content like this :) Just make sure not to post it all over the place ;)
