Aion has placed a temporary restriction on whispering in today's patch. Anyone below level 5 will find themselves unable to whisper their friends until they reach the magical level, when they can once again make use of the function. In practice, this makes whispering very much like the general channel, which is also restricted to only those characters above level 5.
This is only a temporary restriction while the Aion team works out a solution to keeping the gold spammers off of their channels once and for all. However, in the meantime, looks like we're going to have to suffer a bit.
Today's patch also fixed a few things for the French and German language version of the game -- mostly localization issues, along with spelling, punctuation, and grammar. Pretty basic things, and nothing to write home about. If you're interested in the breakdown, check out the patch notes on Aion's PowerWiki.
