The 7th Invest in M.E. International Conference takes place in Westminster, London, on June 1, 2012. I checked out their website, and it states that attendance is by pre-booked tickets only. There are some concessions available on tickets for M.E. sufferers on a first-come, first-served basis, although combined with travel, the day out could easily approach a hundred quid. Combined with that, I don't think the average M.E. sufferer could venture down to London for a whole day. In my own case, I realize that it's not a good idea to plan major outings in advance, as I simply don't know until the day whether I feel up to going out or not.
It seems that you can purchase a DVD of proceedings, including DVDs of past conferences, so that might be one option for those of us who cannot attend. I would also like to aim at some point in the future to set up an online M.E. conference for free that anyone can tune in to from the comfort of their own home. Just this past week, I tried out some webinars offered by the British Council and Oxford University Press. They had attendees from all over the globe, and it was so comfortable being able to opt to join right up until the last moment. Oxford University Press in particular had excellent online software for the purpose. They used Blackboard, which had a range of participant options from chat to voting polls. The British Council, on the other hand, used Adobe Connect, which while good, did not seem to have such good features as Blackboard.
For the Invest in M.E. Conference site, click here. I'm hoping that someone will be able to YouTube it, although guess that the reason why Invest in M.E. has high charges for the conference and the DVDs is that they donate some of it to M.E.-related purposes. (Admittedly, I haven't gone through their whole site, yet.)
