There was an issue at some point with the edit timer not
understanding zero or -1 but i believe that's fixed now.
Have you checked your user groups?
Which group are they in?
Then can you check there group permissions for a forum?
Example :
user = Read write
Ive moved on to 7.15b so i'm trying to rememebr any issues
i may have had with 7.02, but i cant recall that issue
being posted by anyone?
Just checking my control panel now, for more possible solutions
