I chose my username b/c I wanted to come up with a cool username when the name-change update came, and I came up with TheeDeathCaster; thought it was cool.
Although, I miss my old username: stormdragon23
That came from when I played W101, b/c the Thunder/ Lighting class - there was a dragon spell - looked awesome to me, and was the most powerful when I played, so I went with stormdragon on R, but it was already taken, so I chose to add 23 at the end, thus how I came to stormdragon23.
(I miss my original acc name. T-T If I had the R currency, I'd change it back. Ah well.)
If the answer is simple enough to answer in a comment, I don't think there's any problem with leaving a quick comment. As an example, if someone's entire problem was that they misspelled "workspace", I think leaving a comment to inform them would suffice.
