Hi Janny, welcome. Saw your pic over in the Gallery, too. Nice to 'meet' you.
A way to figure that out is to check out the forum descriptors under each forum title header, here:
Forum Index
i.e.,
Quote:
Security & Privacy Issues
OS/app security updates, virus reports, securing systems, privacy, spam.
|
and so on.
If you really can't decide where a topic goes (and it happens!

) then you can just post in General Discussion or, if it's tech support needed for an undefined topic, Tech Support.
And don't worry about it too much. You can always PM a mod to have something moved
