HMRC's agent login page does just that. As a tax agent I have more than one agent id. Several, in fact, as a result of office mergers. In that case it is not I think any design aspect on the part of the web page designers but a feature of windows o/s and/or web browser software. Anyway, on a single terminal I only have to log in once under each id and then next time I just have to click the focus in the id field and it pops up all ids used in the past (provided that I accepted the security prompt to memorise it when used first time). I would expect this feature to be present at any site visited by a windows machine. Ok in this case we are not in windows but I think that the precedent is established.
As to how many users have more than 1 id, we can only speculate. I would expect every starred player to have an alternate. I would expect any player who occasionally wants to post hands in this forum without it being easily traceable back to him through myhands to have one, even though there is no hiding from bridge browser. Several of my acquaintances I know for a fact have more than one, for additional reasons that I do not always know but can guess.
At the end of the day, the value of the suggestion (as any suggestion) can be quantified as the ratio of usefulness to difficulty of implementation. So far you have questioned the numerator of that ratio. I think that you have evaluated that parameter in error, but we can agree to differ. You have not attempted to address the denominator. If it is hard to implement then I have to accept your judgement, having personally no expertise on which to draw. It would however surprise me.
