Leading DN seller offering full return of my TM DN

[RoToHead]

Is there more to it?
The Leading DN seller is now offering full return of my TM DN - I had posted here: "Leading DN seller offering my TM DN for sale " on 8/31/06.

TheAtomSmasher.com was the example, when a Big Name National DN Seller Corp (bnndnsc for short) was offering the DN for AtomSmasher.com for sale (less "The").

I had the Registered Trademark for 9 years and an active business and website.

I sent a C&D to bnndnsc, and gave 10 days for full release of DN to me as TM and DN owner - they would not return phone callsor respond to served letters - for two weeks - then, today a call from bnndnsc Legal, then I received a pdf offering the DN be transferred to me, as D&C requested, in exchange for signed agreement not to pursue TM infringement, Cybersquatting or other action against bnndnsc.

Good Karma? The Right Stuff? Believe it? Other considerations?
