statistics for forum adminstrators that are "at a glance" and more "actionable"
 

I don't think I remember the last time the statistics section in the admin control panel got some attention.

I'd really like to see vBulletin's built in statistics get an overhaul at some point to:
1.) give a "heads up" display summarizing the current statistics all on one screen in a neat graph showing you the overall trends over the year/month at a quick glance so you could be instantly aware of the activity trends of your forum. Currently you have to drill-down each different category which is unnecessarily time-consuming and basic compared to the sophistication of the rest of the software now. It also doesn't give you a good picture of how the stats relate to eachother (e.g. how new members* threads* posts* visits* etc. all relate to eachother* where a consolidated view would be both easier to use and more informational seeing the data overlaid or on the same page.)

2.) focus more on "actionable" things in addition to the basics. For example* unactivated registrations* unanswered posts* attrition rates of different usergroups in terms of forum activity/visits/replies* a quick summary graph of individual forum activity (this one has grown steadily over the past three years* whereas this one is a flat line* whereas these two really declined in activity after I split them...) If you require location or other demographic in the registration (or have it as optional) demographics could also come into the forum stats.

Additionally it would be userful to focus on other areas for the administrator / moderator where data can be provided at a glance to help - e.g. top rated threads of the week/year* if you use the reputation system top rated and potentially problematic posters of the week/month/year* etc. It would be nice to see at a glance how many and/or which users were running into attachment / PM limits. It could be nice to log errors so you were flagged if members were hitting permission error messages to see if you need to tweak something; it could be interesting to log searches so you could see what is being searched most commonly and also if there were a high number of searches turning up no results for a given search phrase for example you could consider addressing these areas with an article in the new CMS* etc.
