The forum by default operates on a desktop version and not a mobile so it will be better on the former but you can easily get used to either.
The new forum software should have a mobile version, so expect that for whenever that gets released.
While using your personal computer to text on the forum is very enjoyable, it is not as convenient as using a phone when you are stationary. Additionally, even though the forum is easier to see on a laptop, what will you do if you see the login on a TV using your computer?
Make use of any device of your choice to login to the forum and enjoy the suitability of what it offers here, but you need to remember one thing about using either the computer system to operate the forum or the mobile device.
1. you can be able to undo and action on the system which you cannot use such feature on mobile device
2. there is word suggestions on using a mobile phone to operate the forum and such improve they typing speed you may require while on system, you will have to use the word suggestion or dictionary function before wrong spellings could be corrected
Whether we are using a phone or system, the difference is very clear and we need to understand that one need to go for what best works for them. There are people that are quite addicted to the use of system to work and you don't expect that kind of person to keep using a phone especially when the features the person mostly use is not available on phone device. It is very important for us to go for what will work for us so that we can keep enjoying the community without stress.
