Thanks for all the reply! I may not express myself well in my previous post. The fact is, this is the only one perl site that meets my "high quality" standard in my 3 months of searching for "good perl sites". So, after feeling so happy , I was wondering "why it took me so long? Is this the only one , or there are lots of others that I was just too stupid to find out?"
I guess u guys answered my question. That is "this is THE ONE". Well, I feel more assured about my searching skill now. Thanx guys :=)
