Have those of you having difficulties with Bub Hub emailed the site administrators? They are very quick to reply. I emailed them last month to try and get the time stamp for posts corrected and they got back to me within hours.
The more people who complain, the greater chance of action.
My access and appearance of Bub Hub has not changed, oddly enough. But it affects me as there are fewer people posting, and I miss you all!
