hmmm...
OK I was clicking links on ClickThru.net when I come to nozol.com and so I take a look at their ToS just for the he*l of it.They have this in their ToS:
"Due to the consumption of system resources and overloading of the e-mail server, Nozol.com forbids the use of the Gossamer Links program by any client."
Now I use Gossamer Links on 4 of my sites and have no problems. What am I missing here?
