This command should use msg.channel.send() instead of msg.reply() to be consistent with similar community behavior reminder commands in this codebase. Commands like !crosspost (line 135) and !gender (line 804), which are also in the "Communication" category and have titles starting with "Please," use msg.channel.send(). The msg.channel.send() approach is more appropriate for commands that are typically invoked to remind or inform other users in the channel, rather than to respond directly to the invoking user.

The help text should not end with a period to be consistent with all other commands in the codebase. Other command help texts like lists all available commands (line 62), provides a no cross-post message (line 132), and explains the XY problem (line 184) do not end with periods.
