...but it's just irritating to the users who used the editing feature as it was intended to be used.
Yes, and so is the behavior of those users who don't use it in the intended manner. Unfortunately,
I don't think the Admins want to get in the business of setting different limits for each user
based on their posting habits.
I don't blame the hosts for trying out a new feature, discovering problems with how some people use
it, and then looking for reasonable compromises rather than shutting it off entirely. In fact, that
is how I'd expect a site to be run.
So you live with the fact that there might be an occasional extra post to correct or add something
after the time limit has expired. Oh, well. It's not like we are paying a fixed rate per post, so we
have to cram everything into one to save money.
For me the important thing is that the website supports interaction and information sharing among
members. An occasional extra post isn't going to affect that.
(But I'm used to a 2 minute window on another site specifically because one user abused their
5 minute window, creating an inflamatory post, then editing it to be much more reasonable after
getting some steamed-up responses.)
