Expiration of events

Is it possible to make events "expire" and not show up after the date of the event has passed?  In other words, show only events with date of today or later?  Or do I have to delete them manually?

As you know, events now haven`t  date of ending (this field only for admin side).

So here 2 ways:

1. enable this for users too, add validation etc

2. add life time (some GL param for example), and use it to :

a. displaying only    b. possible add to cron jobs to auto cleaning its  :)

both ways mean changing current code, developing

Another case of "should be included".

If should, it must be included in develop tickets,

write your offer to support, and our bosses will solve - need it include in version or not

Why do you add all these features without the simple tools NECESSARY

to maintain them???
