Blocked IP Addresses
There's been a number of users who've suddenly found their IP addresses blocked this morning, so I won't reply to each individually, but I've forwarded those who've contacted us to the forum Admin, and hopefully we'll be able to resolve the issue soon.
It looks like these are a result of the IPs used on some old spam messages, which for some reason have just now been activated as blocked addresses in the system.
I'll add more detail here as soon as we know anything more. Please bear with us in the meantime.
