Very strange.
I have the option enabled that members can start a conversation with me and thus you should see a button "Start a conversation". Maybe there is a flaw in the forum software?
I could contact you, sure, but the problem is that I have many messages and there is no search functionality built into conversations and therefore I prefer that I receive the first contact/conversation since I can more easily see (and in future find) conversations.
Maybe Erel can help to fix this?
