Is there any way to see the IP address of where a person logged in from?
actually yes, we can look up the ips for all the recent posts you've made, and they all come from two ips that you have been using for all your posts.
don't forget that the time stamp refers to central time in the US. or rather, its showing what YOU set your time offset to be from the server time so make sure you have that correct.
so i think there are two possibilities -- either you really did wake up and make a sleep post, which is kind of a fun idea and seems possible. or something else got screwy on the forum and someone posted a reply and somehow it got recorded as from you instead of them..
