There seems to be this idea that Facebook is just to socialise and show yourself off etc. Which for some it is. But for a lot of people, like me, it is for the groups on Facebook. Groups which cater for all sorts of plant interests as well as other interests of course. I read somewhere the ones who socialise go for Twitter or similar, anything new, and Facebook is increasingly being taken on board by older people. If you do consider joining FB, I would suggest you use a pseudonym. I regret I didn't. Don't give any information about yourself. And check your profile and untick anything which affects your privacy. Having done that, just look for your interests. Ina
