I visit a lot of time many of the sites. Almost all of them require me to register on their site to continue. However, I cannot remember my username on all those sites. Moreover I don't have so many usernames which can be unique on all those sites. This is the reason why I need a software which can handle this kind of stuff. I just want an application which can generate username's for me which should be unique for a site and I can make a note of it for my further login. Is there any username generator which I can use to generate username for me?
