Hello, this post is assuming there have been no major changes with the forum design recently, I do not have my phone available to be certain.
Last time I tried to read a thread on my phone it wasn't easy to do. The content was too wide and scrolling sideways for every line isn't the way a "big money" community forum should function. Simple question: Do you use this forum on a smartphone, or only on bigger screens?
I use smartphone to do most of my activities in this forum and it works just fine for me. Perhaps it may be the type of phone you are using or you are simply accustomed to using a computer which was my case. The text will be smaller phone but you can still see the entire page without having to scroll to the ends. However, PC gives a better and easier use of the forum since it is bigger and you can open multiple tabs. For posting, PC is also great for that as it allow you easily quote multiple people in a single comment without much stress unlike mobile phone that is a very strenuous thing to do.
I've been using smartphone as well in some of my posting activities most especially when I'm out of my house and need to post so I won't be running out of time. If you can use a much more updated smartphone, that would be a lot better.
However, it's still more convenient to work on your PC because the screen is not limited and you will see everything in just a single view, unlike in smartphone where you need to drag it first. But overall, if you prefer working on your smartphone, still it won't be a barrier to finish your posting activity.
