if I'm not mistaken, u can do global settings in glftpd with the use with *.
Like "site change * max_dlspeed 10" and then all the logins on the site would have max dlspeed to 10kb/s. Would be cool if we could do that for grps too, ie: site change =ioFTPD max_dlspeed 10, so everyone in grp ioFTPD would be capped at 10kb/s download and so on.
