My first chronological 'blogging pen pal' is going to be Dan Q and we're going to exchange emails during December. We've been reading each other's blogs for a while and had the odd exchange here and there but nothing too in-depth. This will be a good opportunity to get to know each other better.
Dan echoes my sentiment about not posting full conversations and, in his own post has said he will post a summary after the event. I think that's a good way to handle it.
I think I'll use that approach as the basis of any interactions I have and will make a page accordingly.
