Well, I finished up the GUI, Just started the scripting. It includes changeable settings through RTB, Including Acces Rights*, Need to be approved by host*, Max lines of script, Blacklist* and several more.
I've also started on the upload function;
1. Check if player has upload rights
2. Check for blacklisted functions
3. Upload script to server
4. Check if player has exec rights
5. Exec script on the server.
* = host changeable only
