If I may ask, why did you choose those particular LLNN.com. Did you envisage a model number for a particular product that may prevail over the coming years?
I chose FC36.com for obvious reasons
I also purchased F33S.com which happens to be the model number of a Luxurary Yacht.
TM82 which rolls of the tongue and could imply Trade Mark
I just ask because this fad of LLNN or NNNN or whatever seems like there is no real forward planning for what the actual Letter and Number combination actually is or is going to be from a marketing perspective.
