Thank you for the plugin. A major asset is that it's translated into other languages and is simpler than other bloated plugins out there.
On my theme I noticed when you click on the Send button the share box shows as being under the sidebar, so you can't see the whole content: http://i.imgur.com/avb5GvL.png
I tried looking for the CSS so I could fix it with a Z index of sorts, but I couldn't find the specific CSS.
Do you know how I could make it show on top?
