Did a search for this but didn't find anything, so wondered if this was unique or if no one has reported it:
When you reply to a post on these forums using your iPad, when you click on the submit button, you get the error message that you can't post empty replies - even though you have a full reply typed out. I've tried copy & paste to a new reply, and retyping, but this happens every time. Net, I can read the forums on my iPad, but I can't post anything.
I haven't tried creating a post - presume it's the same, but switched to a PC to post this one.
