Maybe they respect what you have to say and would like to have you marked if they ever need to get clarification. I know I've got a few people marked whom I haven't spoken with.
Last night Reeka and Blademaster added me to their conversation. I hadn't spoken with either of them through MSN. It was a nice conversation.
I think you have a lot of respect at this website. Others might want your advice. Face it Shadowstrider, "you're popular"
LOL
