I know I am probably going to get flamed for this, but here's my arguement against the 25th rune:

Numerologicly, having 24 runes makes sense, because 24 divides neatly into 3 aetts. The blank rune has no set that it fits into.

Even more importantly, however, the blank rune is redundant. The mysteries given to the blank rue are already a part of Perthro, rune of the unknown.

I also have a third reason I do not like the blank rune: by definition, each rune has certain attributes or qualities that make it a rune. One of these attributes is the runestave, or actual form of the rune. The blank rune has neither form, or phonetic value.

I understand that others may have a different view, and may not agree with what I have posted. I hope we can open up a respectful debate concerning the 25th rune.  

My opinion?  Well, I base it upon historical precedent.  Mainly that the runes are well over a thousand years old and that the runes we use should be the runes of that era.  There was no blank rune back then.  I think the blank rune came in the 1970s or 80s.  Regardless of whether people in the modern age think its necessary, the runes of Odin and the Germanic people didn't require it.  That's good enough for me.

I have a program that has the runes on it.. I love it~!!
The blank one, Some days I like it some days I'm like "K" I seem to get that one alot...

Is that the program from this site or a different one?  If it's a different one, the name of the program would be appreciated!  

I also agree with you. Blank Runes serve no purpose and the first ones ever made did not contain a blank rune. It was added on later.
