The traffic on PW seemed to be very low and it may not have been worth the expenses of keeping the site going. P.ie seems to have database issues and there doesn't seem to be any tech expertise amongst the mods or the admin. The last time there were problems, the work had to be out sourced to an American chap who has a good reputation with the forum software.
Running database servers can be quite a daunting task for people without any background in software and database administration once it goes beyond the simple click and drool web interfaces. Index corruption (think of indices as a kind of phone directory. When the names and numbers get out of synch, things can go wrong) does seem to be a common feature with some forums.
