Post counts and karma aren't cross-compatible between the different SMFs.
As in... when the profiles were ported across, I had 2756 posts.
I've made one post in HSC, one post in WACE and nine posts in VCE.
My post counts are 2757 in HSC and WACE, and 2765 in VCE.
Similar deal with the karma. You and Bob +ve karma'd me in VCE. My VCE karma went up, but not in the others.
EDIT: Wait, I'm wrong.
Posts made in HSC and WACE are recognised in the post count of VCE. However, the reverse is not true. It's one-way. Someone please karma me in HSC, so I can see if the same is true of karma:

Karma is completely separate. Karma in WACE and HSC is not recognised in VCE. Karma made in VCE is not recognised in WACE and HSC. WACE and HSC are also completely independent of each other, both in regards to karma and post count.(I bolded so it's easier to skim-read and get straight to the point, not because I'm trying to be obnoxious, lol)
