When listing Events in the backend the list is way to long as the list option is "All Events" by default. This brings two questions:
a) is there a way to set the default to "Published" so only upcoming / active events are seen
b) any recommendations as to archiving of old records - the web site is only in production for 3 months now and this is going to become a nightmare soon - there are multiple courses running per week every week.
We are releasing 2.6 later this week that has many new options... one of which is archiving. So your issue will be resolved in a matter of days What our site and your email box for the release news.
