Which strings?

I have translated my blog from English to Finnish. There are a couple of strings which are hardcoded into the source like You are here in Dashboard.

The rest should be translateable via messages.po.

Hi,

These strings won't work in my messages.po:

Messaging
Contacts
Contacts list
Comversations list
Compose new
New thread
Recipients
Enter comma or space separated logins
Multiple recipients:
Group discussion
Individual messages
Please enter a subject
This skin does not provide any configurable settings.
This field cannot be empty

In which file do I find these next ones?

You are here:
You are running the latest stable version of b2evolution.
