Many thanks for all the helpful and encouraging replies and comments.
With regard to Theymos and name changes. My understanding is that donators are allowed to do this, and I think he has stated that he may include this as an option for a possible rank above Legendary. At the moment he is reluctant to make any name changes, and has only done this under exceptional circumstances for long standing senior members.
The possibility of my changing the Jet Cash name - I have re-read this thread, and I have come to the conclusion that my obsession with associating a .com domain name with a board identity is unreasonable on the modern internet. Whilst is is an advantage, I do not believe that it is essential. I have been a member of various forums since the last century, and JetAid is the first board identity that doesn't have the .com associated with it. Branding is an important consideration, and I feel that "Jet Cash" is my brand, together with the black cat avatar ( which I also use with my Kuffy identity). I received a lot of criticism when I changed my avatar, and as a result, I changed it back. I have decided to retain both the sobriquet and the avatar whatever happens.
The use of the "Jet Cash" name associated with a payment service. I registered the name in 2002 to brand a payment service associated with my Baronets domain name business. I have used it as a private facility since that time. When I joined Bitcoin Talk, it seemed the obvious choice for a name, as Bitcoin is a tremendous payment method to associate with virtual assets ( amongst other things). I have considered creating my own coin, but have not taken any steps towards creating this product. I will not use the Jet Cash name for this, so any coin using this name is not associated with me. In fact any payment facility that is not mentioned on
The official Jet Cash site is not associated with me, and therefore it should be approached with extreme caution.
The Walmart use of the name - Walmart is a large marketing organisation with a strong capital base, and I believe that any payment service that is wholly owned by the organisation can be used with confidence. Walmart owns the domain name Jet.com, and they use this to provide an online retail store. They have used the phrase "Jet Cash" to facilitate payments, and to provide bonuses for their customers. To be best of my knowledge, this is the only alternative reputable service that uses the "Jet Cash" name.
