I’ve been registered with TPS for quite a while now and it’s led to a much quieter life with those nasty sales calls occuring very infrequently. It really does work. If you live in the UK and haven’t registered – do it! It’s free and really is no hassle.
Talking about TPS while in Luanda someone mentioned that they also run MPS, Mail Preference Service, which aims tor educe the amount of junk mail. Junk mail is incredibly annoying (though my shredder always seems happy to see it :-)) and a total waste of resources from an environmental standpoint. I’ve registered with MPS (also very easy and straightforward) and so hopefully the new year will see less junk mail.
