yep Tanya what Eileen said, these blogs are for whatever is in your life, your kids, your nappies, your thoughts, your work to sell, but yep dont post comments on other blogs directing them to your blog where you have things to sell (like junk mail

)
you can advertise yourself on your own site as much as you please because we can always click off it, but doing it on anothers persons site or emailing them is undesirable.
I haven't posted a "minimum" on updates like some rings do, because we are mums first and bloggers second and like Joh said sometimes it's a low fluffy period! But ther's a few that haven't updated since they joined, it's not mandatory but just makes it more enjoyable "ring surfing" lol
