Basically, this is a very fast public command spell checker. Usage is !spell It has a 50 character word limit, and it will not process more than 1 query every 3 seconds (in case of flood). It will search for an exact match. If it cant find an exact match, it will return suggestions. This is very fast. It uses dict.org, so your firewall must allow access to port 2628 on dict.org for it to work.
