Our website Joomla upgrade migration will begin today - Tuesday May 12.
Any posts put on the Forum from now until the process is complete could potentially be lost. There is no problem with doing postings, but if it's something you want to keep on the site forever, it may just need to be re-posted when the migration is finished if you find it has disappeared.
Everything that is in place on the website as of today should not be affected.
It's like upgrading our behind the scenes operating system to a new version of Windows or IOS, only it may take 1 to 2 weeks and requires a lot of hands on work and testing - not as easy as tapping a "GO" button.
