[saden1]

I must confess, I have a very weird pet peeve. I hate it when people write saden1 as Saden1. saden1 is not a name therefore the first letter shouldn't be capitalized.

Username etiquette dictates the following:

1. Write username as it appears (this is ideal).
2. A username can be written in all lower case (i.e. smootsmack).
3. A username postfixed with one or more numbers can be truncated to just the alpha characters (i.e. Mattyk).
4. If you're going take the initialism route, capitalize all the characters (i.e. AMD or TMC). Initalism is ideal for long usernames.
5. You may truncate the username but only if it makes sense in the context of the discussion (i.e. Ghetto).
