Aspell-net is a port of the GNU Aspell for .Net Framework. The library itself is open source, and is under the LGPL license, but the english dictionary for aspell is mentioned as copyrighted on the sourceforge.net project home page at http://aspell-net.sourceforge.net/
Did any of you guys use aspell-net before? and what license did you release your software under? The project I work on is a commercial one, and do you guys forsee any problem? Should I pay for the aspell english dictionary?
Thanks.
If you download the English dictionary for aspell, in the archive there is a "Copyright" file. From what I see, it's free to use. There are some provisions to include the copyright note, but I would guess it's only if you distribute it.
You can always send an email to Kevin Atkinson (the author) for more details.
