I've been trying to lurk on the Programmer's site and a couple of other new Stack Exchange sites before posting a question to get a higher reputation. My ID was automatically associated with my other Stack Exchange sites, but I still have under a 15 reputation on some of these sites.
So, I can't vote up questions or answers to show my interest in them, and don't feel comfortable adding answers to a question if I don't feel it will add value to the conversation.
It would be nice if a minimum level (15) reputation was automatically added when an ID is automatically linked.
PS. Arrgggg... can't post a second question right away, my retation is too low, so I have to wait for 20 minutes to ask this question. This seems like a bad thing for the meta site.
