Swarers:
Though i've never been able to access the ftp since mode changed from PASV to ACTIVE, i could live with it since i could still find the same staff from other sites(though more time need). And I could understand the reason:

this FTP might behind a firewall with could not recognize passive FTP flow state(see RFC), so change pasv to active is much easier than to change the firewall :-)

Anyway, this is good site out of unpaid hard work, we should respect those who works.
