My apology. I have just been informed that wordpress has been displaying some inappropriate advertisements on our web site. I do not get ads when I view the pages, so I was unaware of this. Thank you to those who took the time to let me know.
I have now paid to upgrade the site from a free plan to a paid plan which should remove the ads. If anyone does still get ads, please take a screen shot and email me so I can take the matter up with WordPress.
