Admin Control Panel 3 :
Another cool feature added in phpbb is the template caching system and better handling of themes. Plus the all important module support which holds great things as far as hacking community goes.
Styles
what refreshing change finally.
first and major thing is that there is support for template caching.. yay..now knowing vbulletin this is an awesome feature and removes the compile time performance impact. (apart from caching queries btw that support also has been added)

The template editing seems to be a breeze. quite a few options exist to integrate the code.
I am not going into much detail here cos if i do i guess thats the only thing i will write about. you can check more about the template engine from the
official support site
Maintenance and system options
Some very good controls have been added in this section. Notably backup has been streamlined and search index spider tracking. Read More below.
Maintenance Options
logging options -> extensive logging options are shown on one click and i love them. there are separate options to show logs for users, admins, mods and an error log.
Backup and restore -> options to run a gzipped backup from within admincp and restore it exists. the interface is nice and easy(like everything

)options to store and download, store only or download only. (I am just impressed by the attention to detail here. There are somethings you realize once you use a software, phpbb has it from the start which is quite grt.
search index options exist to to build your backend index.
System options
First thing you notice..there are options to track search spiders. shows the last visit time plus it has settings to what to show to what spider. extremely good control options.
Then there is mass email option(per usergroup or per persons. I haven't been able to test it but i reckon html is not supported? (or is it?)
report manager exists for pre defining report post templates. a very nice feature this.
And finally the biggie,,, the module support. Making it easier to write modules and extend the features of phpbb. I see module approach being followed by almost all products coming out and is really grt to see it here also. Again i ahven't really tested it enough to comment anymore on it. It just looks good that its there.
My Take : Rating for these sections -> 8/10
