[Nik] Well - I didn't anticipate any loss of data but I never thought having too many backups was ever a problem! I'm using MySQL 4.0.12 here without difficulties. The main bonus is subqueries (not that I use these at the moment) but there is a slight difference in the way certain priveliges work, so you might find yourself saddled with some additional admin overhead if you were to upgrade. I know nothing of apache 2 - last I heard it was "experimental" which I understand to be a euphemism for "best avoided".
[DrQ] The JAM reference: IIRC, around the time of the Aussie Jungle Japes, a group of D list celebs 'volunteered' [paid obscene amounts of money] to go abroad for a filmed Celebrity Detox Week [Ch4?]. Along with most of the viewing nation, I didn't watch it but in an effort to generate interest, the red top coverage glorified in the contents of alleged celebs bowels after CI. I'm told it was a load of sh*te and believe none of them have worked since.
