I've just moved to Hertfordshire so don't know a soul so to fill my time I recently started blogging. I've had a sneak peek and yours is fab. I'm wondering if you could give me some tips on how to start reviewing or getting myself noticed out there? It's something I feel i'd be good at but don't know where to start! Any help would be appreciated
