Sometimes, specially in muliteserver setup you have to do some maintenance, copyying db, making changes to the systems etc.. and you don't want changes users did in meantime disepeared. Or when updating system, when you have lot of cusom changes to ISPC, you don't want the users see the system in proces of modifying, etc.....
It would be great to have ability switch ISPC to maintenance mode. Which means:
- only ISPC administrator(s) are able to login
- on ISPC homepage will be notice like "Sorry, the system is in maintenance mode, you cannot log in. Please try it later..
