I'm still getting the repercussions from the lapse in attention which resulted in LinkedIn sending invitations to anyone who has ever emailed me. Most people have just deleted or ignored them. A few were concerned that the email might have been a virus and contacted me to ask if I really had sent it. But now LinkedIn is emailing everyone who didn't reply with a message saying I'm still waiting for them to accept the invitation.
A few people have been annoyed by these emails and have asked me to stop sending them. Unfortunately the deed was done a few weeks ago and I have no idea how to put a stop to it. If I had known that it was going to cause this much hassle I wouldn't have even considered accepting someone's invitation but hindsight is a wonderful thing that I unfortunately don't possess and now there is no undoing it.
