We can thank user for the topic, is it possible just to put thanks button in every post in the topic? Will that work? :oops: I do not know how it works, but if we can thanks for the topic we can also give thanks for post.
Nope, it won't work. In standard Icy Phoenix only topic_id is stored when thanking a topic. So if you need to thank single posts you will need to add DB fields (and maybe a new table), alter a couple of SQL and then edit viewtopic and its template.
