Basic vs. Premium members

Sol, what's the latest with regard to how membership works? I think I read that all new members get a free week of Premium. Is that right?

I ask mainly because I just spent an hour doing a detailed inline review for a new member and want to be sure he/she actually gets to see it.

Do you disable the Leave Inline Review button for work by members who can't read inline? If not, that would be really useful.

Thanks
Dirk
