[Solved] Re: [libreoffice-users] entering records

Hi :)
Sorry, i know it's initially more complicated but once you work it out it makes it MUCH easier for 
your normal users to use the database as they don't see any of the complexity used in the design 
process.  They just carry on using Writer.  So there is less chance of them accidentally slipping 
into design mode and stuffing things up for you.  

I forwarded this back to the User List as there was nothing to be shy about and it lets other 
people know where things are at the moment.  Also marked it solved.  
Regards from 
Tom :)

 Reports.  It can be useful to have it do some "filtering or "sorting" so that by the time the
