New Unknown, Uninvited Contacts

[DEP/dodo]

Ever since I installed Google Talk (a whole 'nother story!), I occasionally find a new contact in my list.  It's always someone I've never heard of and with an @gmail.com e-dress.  Of course, I simply delete these, but why is it happening?  ~Dodo

I just found--and deleted--four such "contacts."  I think I also saw one previously and deleted it once before.  As I mentioned, this seems to correspond with installing Google Talk, which I have done twice (uninstalled once and then re-installed).  ~Dodo

They are probably people you mailed in the past, gmail adds them to your contacts automatically.

[DEP/dodo]

Absolutely not, Elihu.  If you re-read my initial post, I stated (in so many words) they are strangers to me.  This has occurred both times I installed GT.  ~Dodo

Thats interesting, were are the contacts displayed?

[DEP/dodo]

In my All Contacts list.  They simply spontaneously appeared.  ~Dodo

I really don't know what to say, I've never experienced anything similar.
