I love reading this forum although I'm 'hot and cold' on how much I log in based on what else is going on and how much time I have.
I'm quiet and not naturally a 'joiner'. I have to push myself to get involved in group activities, and I have to remind myself that I enjoy it once I do! So it might be that non-joining attitude that keeps me from being more active here.
Jumping into conversations is extremely difficult to me although much easier when you can type and submit. But even online, unless you post quite a bit, it seems like you may not get into the flow of the conversation going on. I know when I have occasionally joined a conversation here, I might get no response to whatever I posted. I am sure if I posted more people would tend to respond more.
