first of all, thanks a lot for good work. I have a questions dealing with the import option.
I use a form to register for musicians to play on asession. This form has an export option for the registered people. Now I add these people to the WPTR. Everything works fine.
Now sometimes they have wrong data submitted or I have to add something. I do this manually in WPTR.
The next timne, maybe two weeks later I have a new file and just want to add the new lines into WPTR. Is this possible anyway?
