I have been a member of and contributor to this site for most of the time I've been a part of ELU. I really enjoy my time on here and was proud to be part of the beta.
However, I did notice when I logged in for the first time since the beta's end that I had lost my editing privileges that I had whilst ELL was in beta. I don't at all disagree with the non-beta reputation thresholds for privileges, but wouldn't it make sense for the beta-ers to keep the privileges that they earnt during the beta?
Assuming that the reason behind this is misuse, would it be any different if someone who earnt a privelege at a lower level misused it during beta or production? I don't think so. It's bad at any level.
I suppose you could say it's like giving a dog a toy, them growing attached to it, and then having it taken off them.
