I often thought about it and i would like to make a suggestion / request.
I personaly have no problem with several people uploading the guildlist from guildprofiler. Where i have a problem with is the fact that i have to give these people the roster password. Therefore it would be better to give the update.php a set of permissions for updating the guildinformation. E.g.
level 1) public access - everybody with gp-information may upload and update the guildlist
level 2) pw-restricted access - more or less like it is now but pw differs from roster-config-pw
level 3) roster-admin-only-access - only guildupdates permitted if pw is equal to roster-config-pw
what do you think about it?? i have no idea how complicate that would be but i would really like to have that feature
