You don't necessarily need a hyphen or underscore to space things. My guild is called Razorblade Soldiers just like it is. Just type /guild "Chaos Legion" when you make it. If the guild name is in quotation marks like I just show'd, then it'd work out space and all :D

Good luck with the new guild and what-not. You might want to consider joining an existing guild, though, just because...well, it'd be easier, I guess.
