Thank you Pinoc for your reply.
When I ran addlocale in a terminal before, and chose French there was no error message just a message about rebooting, and when I did there was no change. Incidently, I had already taken megagames off my rep list.
I have just tried addlocale again in a terminal, and this time there was a lot of activity, downloading, checking /testing for updates, and I thought we were getting somewhere, but eventually an error message arrived " Failure to retrieve some language packages ( more details STEP1.list)", but I could not find any STEP1.list file on my computer...
Anyway, I really don't want to waste any more of anyone's time. I don't want to change my English interface, simply(!) certain regional things like currency, measurements, dates etc. since I live in France, also I thought it was rather odd that France and Wales do not figure in the pclinuxos list of countries - although they're in the rugby semifinals - yet Belgium and Ireland do... and they're not....
