[dav_999]

is there any way to get a related words or correct words if user type wrong word example

halp so the script correct it to help etc...

[trigoon]

There is no easy way of doing that unless you hand code in all exceptions etc.

You would have to find a script written by someone else who may have done this and incorporate it into your script.
