So now we have a "Welcome Ad", and basically I could live with that. But when I start a day's CodeGuru activity by clicking the link in a thread update notification mail that should take me to the first new post in that thread, instead I get to the page with the ad, and when I then click "Skip this ad" at the upper right, I'm getting dropped at the forum root page, not the respective thread. But most annoying: At this point the thread that the link in the mail should initially have taken me to will be marked "read" and I need to find my way to the first unread post myself. :thumbd:
The ad apparently is only shown "the next day", where "next day" seems not to be determined by lifetime of the IE session or crossing midnight local time; perhaps it's the Windows session that counts or simply a certain timespan of inactivity. But that may actually not be relevant for the issue at all.
