You need to login again for each Transfer you want to do even though you are already logged into Steemit.

Once done the transfer with your direct message will be executed. And immediately after it will appear in the wallet of the receiver in the history section with your message.

Please be aware that anyone can see your message to this user if they go this user’s wallet.

There are other options to get into a conversation with another person. These are less direct but won’t require any Steem Dollars. 
These options are:
1.	Commenting on the user’s posts
2.	Commenting on the user’s comments made on Steemit
3.	Following the the user
4.	Upvoting the post of this user
5.	Go to the Steemit Chat Forum
