Can't believe that something essential like this hasn't been addressed before, probably because it is very simple to do but after quite bit of googling and searching this and other forums, i still haven't found solution or tutorial on how to do this so..
In Mint 17, and now 17.1 i have shared two folders on local network. My machine is only one running linux. First time, sharing was simple and did put sharing overlay icon on those folders.
After a while i forgot about those and icons were gone so i thought that somehow sharing was disabled. So i right-clicked folder and it didn't show that it is shared already so i've done it again.
Then i installed 17.1 and had problem with seeing network shares at all, and my machine wasn't discoverable. I thougt that maybe those shared folders made problem because they were named with cyrilic fonts like: Филм and Тапете. So i shared them again with latin fonts..

And now everything is fine (solved visibility), except i have all three versions of same two folders showing in shares. And i can share them again and i would have fourth version.
Sharing overlay icon is not showing and i don't know how to remove shared folder. I'd like to remove them all and then share one version of each, and if possible, with that overlay icon in Nemo. That's all.
I hope that was clear and understandable, thanks in advance.
