At the time of this writing, the registered user base for GuildPortal is approaching half a million users. Because of that, more common fantasy-style names are already taken by active users. Even though your name is unique in your guild, GP accounts are global to the service (for example, with a GP account, you can post in your allied guild's forums as well as your own, or even in the forum of a guild that's on another game that you play).
One suggestion would be to try the name again, but with a small variation like adding the abbreviated name of the game you play to the end of the name. For example, if the login name you want is AxeMaster, then you could append the game to the end and try AxeMasterEQ.
That said, we do have an automated process that periodically changes the names of inactive accounts (accounts that have not logged in for a year or more) by adding a _ to the end of the name, thereby freeing up the name for re-use.
Ire Infernus was created to be a fun and relatively mature raiding guild focused on wide range content exploration. This includes all content designed for level capped players as well as organized PvP and social events.
We seek to build a community of like-minded, progressive players who want to succeed in WoW by understanding that some goals are not about you, but about us, the whole over the individual. To accomplish that we need relatively mature (age is not necessairly a factor), respectful, helpful (whenever possible), friendly players who are willing to be proficient at their main class, work together, learn or already know the requirements of raiding and most importantly, have fun participating with other members in the guild.
Our policies will always seek to maintain the guild as a place where everyone can be welcome, respect one another and show that real world responsibilities will not penalize a player unfairly. We will be a group, a family, built on respect, trust, camaraderie, progression, improvement and discovery.
Through these ideals, we will be united in accomplishing both our guild and individual goals.
