some topics don't have a thank you button, these topics also don't have a post count.
Posting just "THANK YOU" without adding to topic, is a no,no
posting to topic adding value, will never get you in to trouble.
Note: is this the topic http://www.sonsivri.to/forum/index.php?topic=47070.msg137135#msg137135
If so.... if invite request are not part of new posts, then topic would never be read...
then none of the deleted users from last week, would never get back in....
