Share on mydomain.com button ///

Hello,

I know you have plugins that let me share my social content on e.g. my fb wall or on twitter.
But is there also the possibility for users to post on mydomain.com using a button (like the share button)?
Can't this be done by a code snipet which I offer on mydomain.com for other webmasters to use for their articles and posts?

(Sounds kind of strange. I hope you get the meaning :slight_smile:

Thanks,
Fabian
