carmalee - When it first becomes apparent that what you thought was idle chit-chat, on an innocuous Q&A website, is actually available to everybody in the whole wide world to read through, it can make you a bit wobbly......
But, if you take a little while to consider exactly 'how much' information you have given away and just how much 'stuff' someone would have to trawl through to make a positive identification of *you*, you may find that you are fretting unnecessarily.
Are you concerned that 'whoever' may follow you onto this site and start posting?
If you have concerns about *any* poster, you must address these to the Ed asap and he will be able to deal with them
If I have misunderstood your worries, I apologise. :o)
