Hi folks,
Just an update. I've had to cut back on the cost of hosting. It was getting up to $440 per month. Which is just not sustainable, given the site isn't as busy these days and I've had less time to post here myself.
Talking with the hosting company I've downgraded the plan, which means the site may be slower than before but the cost is about $100 AUD per month.
Much more sustainable. I'm working on some fine tuning to help improve the site and server performance.
Also some emails have been hitting spam filters. I'm doing my best to resolve this.
