This is Shirotsume, I ahven't actually gotten my password yet (lol).
Post in this thread if your post count is off by more than like 400, and provide a link to your old-TFF profile so I can confirm.
(What happened is that old-TFF's post counts include any deleted posts from topics deleted. Here does NOT.)
EDIT: No, all posts are here. Just not the deleted ones, which old-TFF counted.
