Hey there and welcome to
CompuForums! I hope you post here often and keep us up-to-date with your project.
As a forum admin, some of the features I like to see in forum software are...
-Ajax
-Fast loading [clean code with no unnessesary bits]
-Easy backup system [maybe with even the option to automaticly FTP to another server and delete old backups]
-Easy to create great-looking custom skins
-Easy modding system [have you ever tried the mod system in SMF? Something like that would be great]
-Easy to convert from other software
-Secure!
Again, I hope that you come back often and keep us up-to-date on this project. I would like to try it out when it's released.
