This document discusses key legal issues related to e-commerce, including contracts, business structures, domain names, and other identifiers. Some main points: 1) Contract law still applies to e-commerce transactions, though offer/acceptance can be inferred from online conduct. The Electronic Transactions Act aims to validate electronic signatures and records. 2) Sole traders, partnerships, and companies are common business structures, each with different liability and control implications to consider. 3) Domain names provide a human-friendly web address and are administered globally and within country code top-level domains. Registration requires avoiding conflicts with trademarks and other rights.
