Well, I would have replied last night, but hey - I was in a Hotel!
I'm just having a moan really, not at UKP but at the hotels ISP's, plus the trolls who've caused other places to be added to the block list.
I'm not a software expert, but it'd be great if we were able to use VPN with an access key to UKP, provided by the site. That way it can be accessed and it would be known who is connecting via VPN, allowing traceability in that instance.
Just an idle musing, and probably a right ball-ache to administer.
