Recommendation vs. Requirement

According to Webster, the definition of "recommendation" is:

verb [ trans. ]
1 put forward (someone or something) with approval as being suitable for a particular purpose or role : George had recommended some local architects | a book I recommended to a friend of mine.

•  advise or suggest (something) as a course of action : some doctors recommend putting a board under the mattress | [with clause ] the report recommended that criminal charges be brought.
• [ trans. ] advise (someone) to do something : you are strongly recommended to seek professional advice.
• make (someone or something) appealing or desirable : the house had much to recommend it.

2 ( recommend someone/something to) archaic commend or entrust someone or something to (someone) : I devoutly recommended my spirit to its maker.

And the Webster definition of "required" is:

Need for a particular purpose; depend on for success or survival : three patients required operations.

• cause to be necessary : it would have required much research to produce a comprehensive list.
•  specify as compulsory : the minimum car insurance required by law.
•  [ trans. ] (of someone in authority) instruct or expect (someone) to do something : you will be required to attend for cross-examination.
•  ( require something of) regard an action, ability, or quality as due from (someone) by virtue of their position : the care and diligence required of him as a trustee.>
•  wish to have : please indicate how many tickets you require.

The first question, why would PayPal send an email that "recommends" that I ship to the address in the Transaction Details, but really mean it's required?

Will I sell with eBay again, no.

Will I use PayPal again? Unfortunately, the answer right now is yes. I have a store at etsy.com (http://www.bigmaxsstudio.etsy.com) check it out, great stuff and that's the only way I can get paid.The bad news for Etsy, is I've also opened a store at 1000markets.com (http://www.1000markets.com/users/bigmaxsstudio). They use the Amazon. As soon as I figure out how to promote my items through their web site as well as I do Etsy, I'll move everything over.

Having just read eBay/PayPal's quarterly reports, it's no wonder they are not making their projections.

As of now, my claim with PayPal is still classified as "Open Disputes & Claims."
