Thanks for an donor (who will remain anonymous) who has used his signing key, bbCorrector has now been recompiled. The zip file has now been attached above!
bbCorrector REQUIRES you to have a CGI-capable web hosting account, because you must install a server component for bbCorrector. To get help installing bbCorrector, please post a separate thread asking for instructions. (No, I don't have instructions, but I think there's some old instructions on RIMROAD, I could probably dig up). The GNU 'aspell' binary must be preinstalled on the web server. It is preinstalled on most Linux web servers. If it is not, you can google 'aspell' if you need to recompile it on the web server, for the use by the bbCorrector server component.
