I just uploaded a new version of my Thurisaz Guild Info AddOn. It should soon be available to you and brings some fixes and new features. So be sure to update your Addon!

CHANGES in 0.2:

• New finegrained settings to chose wich notifications per guild you want to receive (all, online changes, level changes, member changes)
• New settings on format of Names in Announcements (CharName, @AccountName or CharName@AccountName)
• New Option to display Announcements not only in chat, but also as an display message. This is experimental and subject to change/enhance. Please report difficulties with display messages!
• FIXED: Text in Guild Roster is now vertically centered.
