It's finally happening - we are upgrading our forum software to the latest version!
The important bit first: yes, we will be importing all forums, topics, posts, private messages and attachments into the new version!

Expected downtimes during the upcoming days:
Sept 22nd/23rd: Website and forum will be offline for about 2 hours.
Sept 24th-28th: Forum will be offline for about 2 hours. Website may go offline for a few minutes.
This post will be updated with more exact times as the work progresses.

The picture shows a preview of the new look.

We've made plenty of custom changes to this forum over the past almost 16 years, some of which are being made irrelevant by the new software, others we've ported but some will not make it (at least not right away).
With over 4.6 million posts and 400,000 users this is a rather big task with many moving parts so changes to the upgrade schedule may be required at short notice.
