After getting a couple of complaints, I disabled one type of ad from the forums, discovering along the way a new asynchronous code which lets pages load faster. I replaced those ads with a new vendor and hopefully that will eliminate the problems.
I also switched the main-site menus back to the single buttons which seem to be preferred by readers. I don’t know why this is. I would prefer dropdowns to multiple clicks, personally, but I will not argue with reality.
By the way, if you want just about all the ads to disappear, simply sign p to be an ad-avoiding contributor at $14 per year. Register for the forums if you have not done so already, click on your name in the top right of the page, and select “Account Upgrades” (or register, log in, and click here). If you have any problems with registration, let me know in the comments or by using a feedback form.
I am always open to suggestions.
