PLEASE REST ASSURED THAT THE POP-UP THING THAT HAS ATTACHED ITSELF TO THIS BLOG IS NOT MY DOING.
I have absolutely no idea a) how it got here, or b) how to get rid of it, short of moving blog hosts (which would mean redirecting everyone to a new website and learning how to use a totally different template just as I've got used to this one...). My profoundest apologies for the irritation.
An appeal to whoever is responsible for planting these things: PLEASE PLEASE PLEASE GET RID OF IT. YOU WILL MAKE YOURSELF NO FRIENDS THROUGH PLACING UNWANTED ADS ON THIS BLOG.
If the pop-up has not gone away by the end of this month, I will indeed move my blog elsewhere.
