I just installed this and same problem as above user, it says Messages but it also shows the wrong postcount. It shows I have 1 post when my count is 200+.
Doesn't look like this is supported. Ah well.
Edit: Disregard, I was looking at wrong profile. Yeah it works. I also changed Messages to Posts by simply replacing
Code:
<dt>{vb:rawphrase messages}</dt>
with
Code:
<dt>{vb:rawphrase posts}</dt>
