As Lee has stated, the plug-in development is still in the hobbiest stages. However, I think it would be a good idea to start now before there are too many possible duplications.
Therefore, I was wondering if those people who have developed working plug-ins could e-mail me the following information :
A) Handle and preferably a contact e-mail address
B) Either the string table from the DLL or the header file, to list the parameters and any return values for each function.
Think thats about it. I'll start developing a document later.
