I've asked my admin and my server has about 12gigs of hdd available now
MY server has a
Pentium3 600Mhz
512Megs of ram
30Gigs harddrive.
Redhat Linux.
The server only has these sites.
1 Paysite with about 350 members
1 TGP with php+mysql trading script (50k daily)
1 TGP with UCJ (50k daily)
2 Toplists with AutoRank script (5k each)
And probably, one of my tgp gets flooded with auto submitters, for about 4000 submits a day
