UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Recent Posts - Exclude Specific Ones

From looking at your post and the IDs that your excluding those numbers are pretty big and look more like POST_IDs and not TOPIC_IDs. Maybe they really are the TOPIC_IDs but to be sure, when looking at the post, go to something like Move/Merge this topic and make sure you are using the number from there.
