Messenger
You can now only send a maximum of 3 messages to a member when starting a new conversation before they reply to you. Once they reply there is no limit to the number of messages you can send to each other.
We have made this change in response to complaints from women about being spammed with messages from men on initial contact.
To give some more insight into how to get a better response from your messages to women we recommend reading this article as well as the comments at the bottom.
