Thanks for yr compliment, clovy. Yes it's very time consuming, took me 1 hr plus to run through the threads. I only do it when I am free, but sometimes when I happen to see 1 thread that's not supposed to be at WTB, or free items thread, I just can't help it but to scan through some or all the threads.
As it's time consuming, I may not do it so frequently,as it takes away a lot of my time. I hv to look after my two kids plus housework and leave me very little time to rest, plus my elder one going to school this jan, so will be more busy.
