What does this mean?

[skeeder]

I am trying to figure out what the following means: Could not find phrase 'error_postcount_too_low_pm'. I get this message when trying to send a private message.
Thanks in advance.

your post count must exceed 7 in order to perform that function.

I thought it had to be a post count of 10, but you're either there now or almost there!!
