Chin Leng, that's a very lame reason for not improving your website structure: "However, till date, we've many times more users who don't seem to mind the current format. As such, currently, the ordering format would remain." Do you mean if people stick around, then you don't improve your website?
This is the main reason that deters me from visiting your forum. If you want to prevent losing forumers, it is good to consider the complaints people have for posting order. Out of all the forums I have visited, local and overseas, this bridal forum is the worst. People stick around here, maybe because this is where most people are, and where they can get most replies. But if you don't improve, once something better comes along, there goes your visitor-ship.
I understand that you are not generating a lot of profit by maintaining the forum but you give answers like people like the alphabetical order and it is easier for people to search. Which good major forums like Hardwarezone, Flowerpod and Cozycot have alphabetic order? Why do they not use it? Shouldn't you do your research and thinking before coming up with reasons, sorry, excuses like that?
