I don't mind looking at all the posts - this isn't a really OTT active topic so it doesn't take much time.
Also, I get freecycle emails from my local forum, and tend to just delete the 'wanted' ones - callous of me I know, but 'wanted' adds don't seem as friendly as the wish lists people post on here, plus if we stuck to a 'wanted' / 'offered' format I would have to post 2 emails every time I wanted to swop something, which would be annoying and confusing for all as the posts shift around and the 2 posts would become separated.
So I'm with georgie here I'm afraid - lets keep it informal.

ps - I would look at a post that said 'magic beans' regardless of whether it had 'offered' or 'wanted' in the subject line too - very exciting! :o
