I'm on work - so can't take a look in the script.
1.) what do you mean ? sorry, don't understan the question right.
always threadid 1 or anyhing else ?
2.) bginstalled iis found in postbit or postbit_legacy. Do you edit those templates or do you use TMS ? and ... only the author can see INSTALLED
3.) admin edit: I''ll do it this mornig in a rush - test it for a short while - works and was thinking it was right. You have to know, the admin can only edit the posting NOT the settings. I think there's no reason for admin to edit the authors settings
When I'm back from work, ii'll take a look in the product and do a post with changes to do it - so, if anyone like, he can do it himself.
Sorry - for grammar

I'll do my best
Regards
