As a rule of thumb - you should never post anything, anywhere, by any means, in any language etc etc that you would later not be comfortable to be quoted as saying. (there is nothing you can do about being taken out of context)
Absolutely right, and great advice.
The only real difference of making the forum private would be to the forum owners - who would see a massive dip in 'spidered' pages in the serps, a fall in revenue and an increase in 'one time' sign-ups using temp email addresses in order to read threads.
Absolutely wrong! The single most common source of new members is Google, and the forum would never have survived without Google indexing our threads. We get a lot of new members from people searching for answers to their problems.
If the forum was only accessible to members they'd never have known we existed, and we'd never have been able to help them, and we'd have twenty members.
Yes, the more members we have the more revenue the forum will generate, but it also means more cost for bandwidth, and more time to deal with spam and moderation. Believe me we don't do it for the money!

The purpose of the forum is to help people. Not everyone is comfortable joining, some people just want to read advice given to others, some want to join and participate - it's all good.
