Every time I sign in on my home PC I get a mail asking me if it was me who signed in. It states I was signing in for the first time. Could that be caused by the fact I remove cookies after each browsing session?
Since your answers essentially are the same, it will not surprise you that I thank you both for the contribution. I must look into my automatic cookie-cleaner to find out if I can fix it right away, or, maybe have to look for another solution.
