Warning: There could be problems if you do not log off the board.
Recently while on vacation in Bogota, I used a public PC at the hotel to check the board. I then used the PC at my friend's house a couple of times to visit the board. The last time at my friend's, I hit the "log off" button.
The next day I visited the hotel public PC and found I was still logged on, from four days previous. In other words, it is the PC being used that is logged on with your id or not... if you log off from another PC, it does not matter.
If anyone answers in Spanish from my id, then it's probably not me... unless the syntax is bad.
BTW... what kind of job you got where you search the boards from work? And are they hiring?
