Welcome to the Community Disperser!
You can either run npm install to grab the steem js library or use the copy provided.
Provide a list of usernames seperated with commas and no spaces or @
then provide the amount of steem to send and a memo for the transaction.
The script uses no externals except the steem js lib and jquery, but as a caveat please make sure your browser is safe, no extensions running and do not forget to clear your browsers cache after use.
