Yes , there's clearly been a change in that regard. But, when you look at your profile, it will still say you last logged in on Oct, 15, 2006 or whenever the last time it was you logged in on a regular login. Also, if you put the cursor over your name at the bottom of the page it won't say what thread you are looking at. Actually, I'm not sure why I started logging in anonymously but I did. I also noticed that when I log in anonymously, my ticker doesn't work. It stays at the same numbers every day. I deleted mine for awhile then just recently put it back up. The numbers have been exactly the same since I created it - lol.
Oh and by the way ..... we have cameras that can see into your living room too so .... there's no anonymous around here 🐖
