Howto: eMule osnovna podešavanja :: Internet ~ Novosti ~ Provideri

What are this credits and why should I collect them?
Credits reward users who upload. The transferred amount of data determines the amount of credits. Credits are not global, i.e. the can only be used on the client who grants the credits.
Credits are a major modifier when calculating the progress in another client's queue. The more credits you have the faster you will advance.

Where can I see my credit score?
To prevent manipulating the score, the credits are not stored locally on your hard disk but on the other client's hard disk. It is not possible to count own credits

I lost /deleted my clients.met file. Are my credits gone?
Losing this file doesn't mean that your credits are gone but all credits other people have on your client. eMule creates a backup of the clients.met file (clients.met.BAK) so you can restore the file by renaming the backup to clients.met.

Are credits secure?
eMule uses a key handshake method to make sure the credits belong to this special client. Credits stored for a user are only granted if this authentication has been successful.

How to lose the credits anyway.
As described above the credits are coupled with the secure user authentication. The secret key for this authentication is calculated from information which is stored in preferences.dat and cryptkey.dat. Should one of this files be lost you will no longer be able to prove that you are the rightful owner of the credits.
If you lose only cryptkey.dat, it is mandatory to delete the preferences.dat file, too.
