The tool is intended for community developers, to allow sending of steem to user en mass. The tool supports sending of a single amount of steem to a list of users it also has a field to provide a memo, which is currently required.
To use simply download the files from the github repository and extract them, then open the index.html file in a CLEAN browser. This has only been tested with Chrome so far.
