Alpha, It drives me nuts these gals reinventing themselves and getting new names more often than they change their tampons, and eccie staff enabling that nonsense.
Its too confusing.
But you raise a very legit reason for a name change. When you were new, you didnt understand all the issues to be considered. You now realize that you need a catchy name that is short, easy to remember, gender appropriate, easy for horny big bucks retards to remember and spell correctly for word searches.
thealpha210 doesnt meet that criteria obviously. Its impossible to remember exactly, even when you may be unforgettable. lets see, alpha, did it have a the in front of it? was the end 210 512 or 830? etc etc.
I would suggest simply alpha if it doesnt confuse you with some other gal. None of those exxtraneous numbers and letters on either end of whatever you pick.
Unlike the reinvent name changes for no good reason that drive me nuts I would be pleased to see you change to a name that would improve your puss board seo.
