it may be you didn't select the topic as a question, just as a discussion, a discussion has no best answer, i don't think it can be changed afterwards.
you have to ask a question when making your posts currently you have it set on conversation. check the tabs on the create new topic bar... the 1 you used to make this thread... but because you have already submitted it as a discussion you will have to ask a mod to change the topic type to question. only then can you select best answer.
in this forum i've noticed everyone help alot with thier bests.
I would say that its not just me that needs thanks, in general there are a good 2-3 dozen who put a lot of thought into helping, there are others that are learning, and those that went before and aren't here any more.
A BANANA will also do, if I'm not mistaken. At least if we ever want to read Shakespeare here.
