@Mike: just reupload an unhacked functions_newpost.php to remove the old hack and then just upload the plugin
@Chris: correct, but the added condition should be placed into the custom condition field in the vbulletin options, that's why i added that field
@possible problems: the merge is just done, if the merged post won't produce an error.
so if the new post would have to much chars or images it won't merge.
also posts with attachments are not jet merged
