We've implemented too much of changes to our database, as well as the forum code to cope with the high amount of traffic the site has to handle on a day to day basis. As many would know, the earlier free versions of IPB (which is what we're derived from) wasn't exactly very well written, and we have modified a lot of code and db structure over the years, so none of the IPB upgrade scripts would work without a lot of modifications. We also have no idea how scalable the latest IPB version is on a high traffic site like ours. (which means we've got to spend weeks of sleepless nights tuning it to work properly!)

We will no doubt look into it, but there is no definite timeline at this point in time as the system is quite stable and we do not have the resources to upgrade the board and ensure minimal downtime to the site. There isn't exactly much new fancy stuff in the new IPB to warrant an upgrade, and we prefer to have a stable forum over fancy functions anytime.
