My answers to your questions Rich:
1) The systems are fine in my opinion!
2) Nope, not for me. They load at a good speed
3) Sort of, at least you place the question on top so we answerers know what we're going on about
4) That would be useful, I never really use "Question Alert" though
5) That would be brilliant. Then I could catch up on my best game answers.
6) It'd certainly help me, I may end up re-answering a question. I don't think I've even done that though.
7) My complicated suggestion of just telling you when a new question is added. I'd love that but it's probably going to be complicated so you don't have to.
8) I wouldn't think it mattered, if it's slowing down the section, I don't mind you moving them. Old questions are usually answered anyway.
Oh, by the way, if you're wondering why I'm posting at this time, my school have a teacher training day today!
