total size by communication type
General communications may total up to 1 GB, but opposition, cancellation and appeal communications are capped at 100 MB in total.
How we handle it: Treat 100 MB as the working envelope when the communication relates to proceedings, and reserve larger totals for ordinary correspondence.
