Preceding unsigned comment added by talk contribs 19 25 7 Jun 2008 Believe me I ve some experience with different types of IPs and those you tagged aren t used by 15 000 students at the same time There s a realistic chance that the warning reaches the user who vandalized And again the IPs will not be blocked unless they vandalize there are some students who want to edit constructively Your edits would only discourage them Please sign your talk page edits using 83
