Re: removing old customer records
I don't know what the rules for the UK are, but in the US most, if not all, business records need to be saved for 7 years.
You can use phpMyAdmin to download those records to a disc and then delete them if you think that is neccessary - however you need to make sure you get all the records that are associated with each other or you will end up with orphaned data.
Please do not PM for support issues: a private solution doesn't benefit the community.
Be careful with unsolicited advice via email or PM - Make sure the person you are talking to is a reliable source.
