OK, So Since I only  have 35 posts and there is a _ in my name, I don't ever have to worry about the other look-alike because we may even like each other???
And besides.. it is hard work for the filter to say that name is taken??
While I do understand the work part.. I do understand I might like this other person.. we haven't even met.. no fault of either of ours.. no other website that I have ever come across allows such alike names...
I guess I am still allowed to say, I don't like it much.. 
I still like visiting.. so guess this is not a democrocy.. so thanks for listening.
