no big difference between user names

[symptome]

Sorry
They remember have answered a post of a "james". But they aren't sure if they answered a post of james1, james2, jamesA or whatever. It is quite difficult for them to remember when just one capital or a number is being added to an existing user name to get a new "unique" user name.
And so they have to read the postings of this member to see, if they're right and remember correctly.
