To keep them all in one place, please post any updates to forum_styles in this thread. By all means post in the original thread so that the requester gets notified, then again in this thread. At the time of this post we don't have a mechanism to auto update forum_styles, it can only be done with a new / update release of IHG.
Anyone who can come up with a way of doing it automatically - like the hostf - please PM the code to Greg. If you've got ideas / suggestions / partial code that you just want to share, post in this thread.
