I should have included this in my previous post, but don't forget that
Thursdays in February are Double XP days. XP gained from bashing and
questing will be doubled for 24 hours, starting at 0:01 GMT on Thursday
(which will be Wednesday evening for most of you in the US).

Please remember, however, that during these double XP days, experience
bonuses received from achievements and tasks will not be active. So, you
will not be able to accumulate very large experience bonuses during the
double XP days. You will only be able to double it. Your achievement and
task bonuses will not continue to count down during the double XP day,
however, and you will still be able to complete the achievements. You
just won't get the effect on increased bonus until the double XP day is
done.

The other, smaller xp bonuses will still be in effect, however. For
example: the owl tattoo, guild xp bonuses, warmasks, and statpack
experience modifiers will still work and increase the amount of
experience you gain. The only change is that achievement xp bonuses will
be replaced by the double xp bonus for the 24 hours.
