Not sure if this is the right place for this, or this is a sensible suggestion.
I'm not sure how the website is hosted, run or anything like that, I'm not trying to tread on the work or the staff, donators or anyone involved with this site or disrespect the efforts etc.
The website does seem to be of a outdated style, for whatever reason, and there are cheap and feasible ways to update this, for example XenForo, which would un-doubt ably be a major improvement and upgrade over the current setup, allowing for much better user experience, upkeep and so on. https://xenforo.com/
There are cheaper softwares out there if this is too pricey.
Please bare in mind this is just a suggestion and I'm in no way slating or criticising the current setup, just thought I might bring it up is all. Obviously I understand there are reasons why the site has to remain as it is, and I'm not going to argue with it, its the owner's site afterall!
