The Stroma e cert software is not difficult to use unless you are a complete IT numpty, it is not intuitive and could be better designed in that you have to enter all information every time you use it but it is free with membership and works. The online portal is also easy to use, personally I do not see any issues with notification or the e cert software. All of the instructions come on an e mail when you first sign up with them, you just have to read them. The software and notifications portal are separate as you get charged 40p to issue a certificate whereas the notifications are free!
