I don’t know about anybody else but I’m perfectly happy with the way it is at the moment. I access the website on my phone all the time & I don’t have a problem, I can find everything easily.
I’d probably hate a tacky, modern style app & I’d probably hate a new modern website too, I’m perfectly fine with the current set up but I’m just one person.
I do not also see a problem accessing the forum through mobile, I do not think that the moderators or the administrators will plan to create a mobile app because of the security and also the features that requires changes.
I get used to it after all so accessing using mobile is not a major problem. I now imagining if there will be a mobile application of the forum and for me it is not good. Accessing through web is still the best way to read and posts different topics.
