I have been getting this message (when I click on the link given in email alert) for various threads (for which I have subscription/commented upon): Invalid Thread specified. If you followed a valid link, please notify the administrator I have no idea what is the issue, and why it is happening; usually after some time when I retry by re-clicking on the thread link it works. Can anyone please look into this and advise. Kind regards and thanks. Edit: Last alert I got was about this thread --> http://www.techspot.com/vb/topic164571.html#post1035511 After about 6-7 tries (and 15 Min. +/-), the same link opened the thread.
