Been working through what needed to be done to phpbb3 to make it a free forums system, the first round is a petty annoyance, phpbb3 caches things, that is good, it is also a problem when it comes to portals, but that's another story.

But caching needs somewhere to cache, and this is one of the things we must change, it should be trivial, as after all any caching system should be coded to allow people to change where the caching goes on, perhaps to a different disk or a ram drive, but phpbb3 hard codes the caching to a directory under the root directory and hardcodes this in loads of places  

Its a small detail, but its sloppy coding.
