Sylent, not a weird question at all!
If you mean what constitutes my mental image of a member here... it is often a sig, but also many times I find my imagination provides me with an image from scratch, so to speak, and there are also a lot of people of whom I don't really have a mental picture: I read their words without picturing a person. A few people who I know very well I see as their pics on Stealthy's Site.
