sorry... but can you dumb it down a shade.
Is this the web config in the system root for the particular dnn site. Or is it the webconfig in the NetSpell directory? (I created a virtual directory pointing to this... not even sure if it is needed).
and is the format of the entry like this?
<appSettings>
<addkey="d:\data\webs\webname\netspell\dic\"value="bin"/></appSettings>
for example?
AND
Where in the webconfig file does all this run?
