I'm sure you don't want to hear it, but if you rank team 10 on 24h Average your 86th so being realist your be in and around cell 88 for ever unless your production increased.

That said all active folders on page one are valuable members of the team in output and total points earned (both being major achievement in their own right - your nearly at 50k - fantastic for a single machine cruncher) - and it's as a team that we're going up the rankings.
Don't lose heart, but your most welcome to upgrade / borg your output at any time
. Your Old P3 is not worth the effort - Barton @2.5 could be worth wild, but electric bills become limiting factor.
I myself only have one personal Pc that adds into the pot (and drains my own), the rest is produced from the office I work in (I've a nice boss). We all play our part.
Not in a million years could I afford Magman's or Stan’s private PC farms. Or achieve LigerZero/Sculptors output - But I don't try too either.
I was as welcome to the team when I just folded on my P3 as Shadowscotland than I am now with Lemonman's farm. Guess it just comes down to why you fold? The team and the science are good enough reasons for me irrelevant of output.
Just my 2p worth
BTW that ranking just puts lemonan (a rushed borg that I can't get back to) ahead of you - It's a Dell P4 2.8 512ram on 24/7. How does that compare against your rig spec?
Edit: see the freecycle sticky for a case and network card I'm giveing away (as your london based no postage either)
