Well, that's a legitimate type of question HelloWorld18 !

I had my DX and MX listed the next day I joined PC, which isn't that far. I noticed some people here do that and thought what a nice idea. It is just a way to show what our issues, diagnoses and experience are with certain meds. I did contact few people who have similar DX and MX to mine, and it was great to share and receive feedback. That's why I joined here. But then again, after sometime, I started feeling a slight discomfort looking at my sign every time I post something. As JD said, we need to think positively and normal. So I may remove them from my sign if it really started to annoy me.
