Also, if you hear of people ‘posting’ or ‘not posting’ or ‘posted’ or ‘unposted’ pens, this refers to putting the cap on the back of the pen while you use it (posting or posted) or leaving the cap on the desk or holding it in your hand (not posting, unposted, or non-posted). Apparently Americans and Europeans have different habits, with Americans posting and Europeans holding the caps in their hands. Having thought about it I think I usually do not post though I tend to leave the cap on the desk. Being a leftie and having a problem with wet ink smearing, I tend to only use fountain pens at home though.
