You are not fooling anyone with your "annonymous" post.

If you will refer to your IP address on your annonymous post ..... and the identical IP address on the post above made by "Mark", it does not take a rocket scientist to determine that both posts were made from the same address. It's sort of like leaving your fingerprints.

Having said that .... one should not have to begin comparing IP addresses or performing searches to determine who made a particular post. If you prefer not to use your last name ... for whatever reason(s) ... a simple "Mark F." would be fine.
