What I Know from some of my posts reviewed by WM, shared here:
At first, the resource you posted put under 'New Submission'. You can see them in the 'New Submission' category under resources. The resources under this category, not reviewed by the editors yet. When you open the resource you can see a message like 'The resource is not reviewed by the editors yet------". Once the editor reviewed it, it put either under Pending/Approved. If the resource has any problem(the reasons may vary), it put under pending and most probably the reason should be in the message like "The resource is under pending-Reason :-----" which can be seen when you open the resource. If your resource has no problem, the editors approved it and credited with needed points and cash credits. So, it will goes to Approved Categories.
'My resources' category only shows your resources which are approved. You can't see any of your 'new submissions' or 'pending' resources under this category.
Once you post a resource and approved, and at a later time if you want to edit it, you can do it. After your editing, it will goes to 'new submissions'(you can't see it in 'my resources'). When the WM reviewed it, it will surely credited with additional points and cash credits if it deserves. Then it will again appeared in 'Approved' Category. In the meantime, the cash credits( sometimes points too) for that resource may not appear in your total cash credits.
The case of Abid Sir, I think , most probably it will be in 'New Submissions' since you can't find it in 'Pending' and 'My resources'. Find your resource in 'New Submissions'. Open the resource and select edit. Hope your problem will solve with this.
