Thanks to Support for providing this link. I never tried top end mobiles, more similar to pocket computers, so I'll share my experience with traditional handphones. I'll probably have to post twice and this brings us straight to the first subject: the characters per message limit. In my case is set to 1024 but that's fictive since the phone's memory will get overloaded at around 600 and every new digit increases the chances of a crash. I strongly recommend the use of a mini-browser. They rely on a remote server that pre-load any page and modifies and compresses it before sending it back to the phone. It means less data sent and a cut on the payments that can reach 70-80%. I use OperaMini.
Using a mini-browser, you can freely switch between the full and mobile version of this website, since the server will block unnecessary graphics and make the pages less heavy. Just be sure to adjust your settings. Turn the images off and the visual effects on: you will see black-shaped empty boxes where the images should be and thus know the position of the clickable images. Also enable mobile view to avoid having to zoom in and out and scroll left and right while viewing the pages which is very annoying. A note: when logging in, the answer to the security question never corresponds to what you see. You have to try until you guess. Me, I never log out.
If it can help, while trying to log in with my old phone I got once a different kind of security check, maybe an old version. There were several numbers and I've been asked to write in the text box the one colored in blue. It worked fine but I would need to try it a few more times before suggesting it.
I'm using a Motorola SLVR L72. Is not a new phone, the person that gave it to me bought it in 2008, but is a huge progress for me. I'm using Opera Mini 4.4 for java phones. My suggestions should be accurate for any j2me or android device. The problem of Auxarc (sorry if I mispell the name) is that he is using an iphone. I read they have serious compatibility issues (some javascripts for instance) because Apple created a stand-alone OS. That's what people say on the web, I don't have direct experience on this subject. About the security answer: I was talking about the desktop version, the mobile version doesn't allow to log in or reply as a member.
On the Registration and Login pages I have removed the image Security question and replaced it with another type of Security check based on a simple math problem which will be changed every now and again. Now you do not have to worry about Login again.
Thank you, that proves once again your attention to any aspect of this website. But that was not a major problem, actually staying logged in works just fine. I believe that most of the difficulties that us mobile users are experiencing are phone or browser related. The website itself is "Mobile friendly" already.
