How would this help?

We have an already established feedback system in place and would want to integrate those ratings into iTrader so you only have to go to one place to see total feedback. I've PM'd you about making this a paid adjustment too. We just need to do it initially.

Could you please tell me how this should look like?

The administrators are allowed to set/edit the amount of positive / neutral / negative feedbacks? Something like that?

Yes, the admin would be able to set the feedback someone starts with and then it would just be added to normally from that point on. Like we can adjust post counts in vB. But to be safe, it could be set so it can only be adjusted one time.

Can anyone verify if this version works with 4.1.3? I installed as admin and am getting an error message, anyone have a similar issue?:

Cruspeed, you do not have permission to access this page. This could be due to one of several reasons:

1.Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2.If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

any1 know what could be wrong?

Fatal error: require_once() [function.require]: Failed opening required '/home/content/11/7796811/html/includes/functions_itrader.php' (include_path='.:/usr/local/php5/lib/php') in /home/content/11/7796811/html/itrader_global.php on line 11

I have the same version and issue

Great mod, Installed and nominated.
Very useful and simplistic.

anyone got any help to offer?

You didn't set the usergroup permissions.
/includes/functions_itrader.php was not found. Possibly you forgot the upload it or is has the wrong permissions.
