Hi Gigazelle,
Thanks for your reply but this is not the answer I am searching for.
We don't want to explain our visitors how to delete the NOTARGET cookie, but we want to offer him a button/link on our website which immediately opts them back in, like Adobe offers from the Analytics Omniture_optout:
Opt-in - Include me in visitor session aggregation and analysis (do not install the kbcgroupnv.d3.sc.omtrdc.net opt-out cookie) - Click Here
Opt-out - Exclude me from visitor session aggregation and analysis (install the kbcgroupnv.d3.sc.omtrdc.net opt-out cookie) - Click Here
Thanks in advance,
Sarah
