I hope it is OK to post a "help wanted" ad here. If not, just delete it and sorry.
I work with an online education company that provides educational services to schools and families. Our products are TimeWriting.com, VocabularySpellingCity.com, and others.
We are looking to integrate a grammar checker as an educational tool but would like a programmer with some experience in this area to work with us on the design, implementation, and integration. We imagine this would be a part-time project for a few months. Ar the outset, there might need to be a trip to our offices (Ft Lauderdale, FL).
If you know anyone who might be interested, have them email mayor (at) spellingcity (period) com.
