...Just want to get a reputation check before I accept/reject the invite.
No experience with MyLife but:
http://www.siteadvisor.com/sites/mylife.com says "tested ... and didn't find significant problems" while 12/12 SiteAdvisor commentators had nothing good to say about it.
http://safeweb.norton.com/report/show?url=...w.mylife.com%2F says "Norton Safe Web found no issues with this site." while the (single) review and user comment says "This site gathers information on you from any source they can get it whether it is accurate or not, and adds it to your profile.
This site will NOT remove inaccurate, untrue, false, information about you.
This site will NOT remove your profile when you request it." and much more.
If you already belong to any social web-based groups, I suggest you check them out on the above and see how the comments compare. If you don't belong to any social web-based groups then maybe a vendor invitation is not good enough reason to join one now (because you probably don't really want to).
[Moving this to the Lounge as it seems to me to fit that forum]
