Yes, I have the same problem. It's not that the people don't know me, it's more the issue that they don't read their email ever, or not too thoroughly. So, my invitation hangs out there in an inbox forever (I have some in my invitation list literally two years old - and, no, LI rarely cancels [or whatever they call it] them), or the invitee deletes it without realizing what it is.
I've questioned LI about his a couple times, they had no real answer or solution. My logic is, if I knew the person's email address, I'd email them, and not depend on LI. Even on the first invitation, the email address isn't revealed, so how would I know it on subsequent tries?
How about this: after an invitation is unresponded for, say, six months, you have the ability to resend with LI inserting the email address again? Or a control setting the reciever can check to not recieve invitations from the same person more than once/twice/three times [a lady] ? LOL

Just an added set of circumstance to add to this thread:
Sometime ths past winter, LinkedIn stopped working on my Vista machine - I am directed to the Home page, "Already on LI? Sign In", and it takes me to the "Sign In To LinkedIn" page, which, when I sign in, takes me back to the "Home Page - Already on LI?...". It does't hang, just an endless loop , but only with IE8 - Firefox works fine. And yes, LI's auto response was to reset the System Date & Time. ??????
The Vista machine is hooked up via ethernet cable to a Linksys wireless router. My other laptop is on XP, LI works on both IE8 and Firefox and is connected wireless to the Linksys, no problems whatsoever.
The only thing I do find strange, though, is that even when I'm logged in (on whichever workable system), half the time when I go to do something which involves sending something, LI wants me to log in again, and half the time it doesn't. Is it a security issue, or a glitch with the cookies?
