identifying posts from active MC.o users??

That's sounds like a good idea. Did you try posting this info over in the "Lists and Recommendations" message board? If not, you can always e-mail the fantastic creator and owner of this website (Jim Smith) at [email protected] too. :)

Well anything dated after Feb 20th is from this site. And anything dated before Feb 13 or so is from IMDB. There is only about a week of overlap where both existed at the same time.

And in those cases, you can just click on the name. If it's a post scraped from IMDB , clicking on the name leads to the home page of moviechat. No profile will show.
If it is a post that was made here, then clicking the name goes to their profile with a list of their other posts..

We're on the same wavelength, whiskeyTango. I've been thinking it'd be great if the usernames on the imported posts could be regular text instead of a hyperlink to the main page, and the same black text color as the rest of the imported post. I think it'd be very helpful for users to be able to tell very easily just from glancing at a post if it's an archived post or not. Having to mouse over a username and note if the username links back to a profile page vs. the MC homepage is too obscure a detail to be user-friendly.

I think this would be very good for morale, too :) because you wouldn't want people replying to archived posts thinking that the archived user will get an email notification. Also, from the perspective of those who might just read the boards (and that might be a lot of people before they decide to join a site), you wouldn't want them to get the impression that many "people" on this site (that are actually just archived usernames) aren't replying back when people reply to them. If it could be clear to everyone including a casual board lurker which posts are MC-origin and which are IMDb-archived, there won't be any unnecessary disappointment or negative impression if imported usernames don't reply back from the void! :)
