Would you like to be an IP blogger? Most of the weblogs listed above are still hoping to recruit some fresh talent into their blogging teams, as well as to host more good guest items from occasional writers. If you (i) have something valuable to say about IP, (ii) have some experience of IP in one form or another and (iii) think that you may be able to turn your hand at blogging (or already have some experience), do email Jeremy here, attaching or linking to your CV, and explain why you think you might be a good blogger or contributor. It may be a few days before you get a response, so do be patient!
