Greetings. I have just begun caching, and came here looking for some etiquette answers. I have a young family, twin 6 yr olds and a 9 yr old, and we have begun this as a family activity. Is it frowned upon to create accounts for my children, and allow them to log their finds individually? The first couple of caches, I logged under my own account, but the kids want to leave their own little thank you notes. As a CO, would you be upset about 3 log entries by a single family? TIA
