short note: I've just finished archiving about 2.600.000 postings in my board. I'll have to make some further compatibility test, than I will release it as hack.
it's another approach, then used by Xenon, and the result is a dramatic increase of speed by reducing the "post"-table by half...

...so the "key feature" of my hack is speed improvment for large boards (> 1 million posts), and not to reduce used space.
I hope, I get the beta released in about 2 weeks!
