We know it can be frustrating when you've spotted someone you like, but they aren't replying to their messages.
However, repeatedly messaging someone who hasn't replied can make the other person feel overwhelmed or even harassed. If someone has received too many messages, it's rare for them to respond positively.
We ask members to only send up to two messages to any other member before waiting for them to reply. An initial greeting and a friendly follow-up is usually the best approach.
Don't worry if you don't get a reply right away. Your messages will remain in the other member's mailbox, so if they choose to, they can reply at a time that's right for them.
