If you would like commercial support for an open source application, you can buy a block of support time online here or feel free to contact [email protected]. However, bear in mind that it will take a lot longer to create runnable teaching examples than with ReportLab PLUS.
The open-source ReportLab Tookit is also supported by the community. The first port of call is the users list, available by emailing [email protected]. The best interface is a Google Group at https://groups.google.com/g/reportlab-users; it's mirrored from the original source at https://pairlist2.pair.net/mailman/listinfo/reportlab-users. Our staff cannot promise to answer directly. Please also bear in mind that if you send us a patch, it may take a lot of time to evaluate and prove safe in all cases so we cannot accept all of them.
