How can I find out if a guild name is available?

Question in title.
If I want to create a guild, how can I know ahead of time whether the name I want is available or not? (Not talking about freaky coincidences of somebody taking the name 5 minutes before I create my guild).

It will tell you the name is unavailable when you type in the guild name.

Well, yeah, but I'd sort of like to know ahead of time

Then you can't.

thats what backups are for

Spit up 1.5m, duh.

But srsly, yeah.. best just agree on an alternate name if the one you want is taken.
