Dear Yii Folks,
We have updated our forum to use IPB (Invision Power Board), thanks to Vadim for his generous contribution of the license to use IPB and his kind of help to help migrating the forum data.
If you find any problem in using this new forum system, please let us know. Most old forum data should be migrated to this new system correctly. We do expect that some attachments or uploads may have problem, however.
