Hi All, Sorry about the warning message. I've had our hosting company working on it, it unfortunately takes a few days to get a new certificate issued and installed.
To explain what's going on.. the security warning is because our site is set as https not http, so it's looking for a secure certificate to encrypt the data flowing back and forth. Most forums don't have this encryption and data is sent through the standard http but we added it a while back just as an extra for encrypting passwords etc. It's a bit overkill but Google likes it apparently. Mainly it's for online shopping/transactions.
You can get around the warning on your browser by clicking on the Advance button when it pops up and then click Proceed.
