The letters-replaced-by-numbers thing is an error we've encountered before, but it seems to just happen on the Question Board. I'll message the site admin, paarthurnax, and see if he can fix that.

As for the name, I suggest looking through the Dictionary to find a few monosyllabic words that best describe you. For example, I like to meditate, which relaxes and focuses my mind. Hence my name: Hahdremro is Hah "Mind," Drem "Peace," and Ro "Balance." It has nothing to do with my real name or any of my many nicknames, but I created it to be something that would describe me as I see myself.  I looked through a list of Thu'um from the game and chose three rotmulaag, or Words of Power, that I felt best described who I am.

You can do the same by looking through this list of Dragon Shouts on the Unofficial Elder Scrolls Pages (UESP) wiki: http://en.uesp.net/wiki/Skyrim:Dragon_Shouts

Keep in mind that each Dovah name is its own Thu'um, and most Thu'um are comprised of three monosyllabic rotmulaag. There are exceptions, but I advise going by these basic rules. Words like se (meaning "of") and do (also "of") are not supposed to be used in Dovah names, and very few canonical Dragon names stray from the usual "three single-syllable words" formula.
