The operational budget for TWF exists primarily due to advertising (it's not from selling T-shirts ). Consequently, we are experimenting with the placement of ads.
There is a balance of proper placement for maximum visibility, and then there is a point where they are just plain annoying and take away from the site. Yes, it would be nice if we could eliminate them altogether but as a free site that's possible.
So, bear with us. The ads you see now may not stay there, they may be removed, change in size or who knows. There are a lot of options and all involved hacking complicated code.
