Tom,
Thanks for that. What actually happens is that when I click on the "Water" section, I no longer have posting rights. I am OK for wind, control, storage, etc. for posting.
After logging in while in "Water", I am directed to, I believe, the standard screen with posting rights. Switching to "Water", the "Submit posting" disappears for me. I was unable to thank contributors while reading the replies to my "Anode" posting in "Water". Had to write a new post. Logging in again whilst in "Water" does not cure it either.
This may be (WAS) a bug in the system; it may not like Australians, although we are not part of the "Axis of Evil", but in the "Coalition of the Willing".
However, am able now to reply to your post - strange!
Thanks again.
Regards,
