Please don't steal. You may be making it difficult for the people you steal from.

I often use the same username(s) on multiple forums where people discuss similar topics because I want other people who visit the same forums to recognise me as being the same guy.

I've found this username taken a few times, and it has bugged me every time. While it is from Tolkien's Elvish, it is obscure and then misspelled (actually a portmanteau). I've had to add a prefix, such as "TheReal" to it.
