One feature that I personally would use is to disable the 'Contact' link at the bottom of the forum screen.
In my case I prefer to get email directly from the sender; The other reason is that the 'Contact' link is a "great" feature for spam mail, and this is annoying.
I guess that the option to disable the 'Contact' link should be in the 'Advanced options' of the forum. (In my case the email is displayed on the screen).
One of the best admin features of my little forum is the 'Backup'. I would love to use it instead of using the cpanel of the server. Yet, every time that I've tried to 'Restore' a database it failed with the message (or something similar):
Error! MySQL error: Incorrect datetime value: '' for column `rapideup_mylittleforum-2.4.21`.`mlf2_temp_infos`.`time` at row 1
If the 'Backup' feature is not reliable, then it shouldn't be there, yet I guess that a lot of users would love to use this great feature. We all know that Backup is critical and we all need it. I would love to see it works, really.
Thank you for this great software.
