Usually included with each resale products is a document named "Reseller Agreement" or "License". This document notifies of the allowable distribution channels that you are allowed to use, or sell this product in. Below are the listed rights and their basic meanings...

Private Lable Rights - Private label rights allow you to make another author's work show like it's yours by changing its content. That can vary from writing an introduction paragraph or editing the title to completely modifying it any way you want and add your name to it as the creator (with or without the condition that you HAVE to modify the content). Anything allowing you to change the content (except branding an affiliate link) is called Private Label Rights.

Master Resale Rights - Master Resale Rights gives you the opportunity to sell both the product AND the resell rights. This increases value of the product significantly, because your customer may resell the product for profit too. You own the software completely.

Resale or Resell Rights - Resell Rights work the same as Master Resale Rights, with the exception that you may sell the product and keep 100% of the profits, but you may not sell the resale rights to your customers, meaning that they are not allowed to resell it!

Personal Use Rights - These are are just like they sound. You are free to use this product but have no permission to sell it, or give it away in any format.

Edit / Alter The Sales Material - Most products in the Resale Industry come with a "Salespage" or "Website". This usually consists of graphics like ebook covers, or software boxes, a page header and footer graphic, background and an "order button" graphic. The salespage also usually consists of sales text already created for you. A general rule is that any Master Resale Rights product you may alter only the sales page text and must leave the graphics as they are, where a Private Label Rights product will usually allow you to edit, or even replace any graphics, and rename the entire product.

Added to a Paid Membership Site - Membership sites like www.enterprisemembers.com are websites that offer resale, and other products to it's clients in a membership format. In short, you may pay say $39.99 a month a get access to all products for that lump price.

Added to Free Membership Sites - Free Memberships are one of two things. First, they are just like they sound, a site that does not charge a fee of any kind. The other is an area of a paid membership site that is not a part of the paid membership but offers free resale and other products.
