First of all, thanks for the service. I'd like to use common lisp as cgi. There is no hosting in the world with that feature. I guess it won't cost so much to add an interpreter for common lisp. The best choice is sbcl, which sure has a binary for linux. And the second one is clisp. Lisp is a very special language and could be an interesting feature to have and call more possible members. I guess it's easy to add it as cgi, since it only needs an interpreter, and sbcl is very available and easy to install. Also common lisp is a very mature language, and sbcl the best implementation. If you consider it, could be a nice feature to add, and can create some interest for a lot of users. Ofc If you add common lisp, specially sbcl I'll say to all lispers that you've added a lisp cgi for that host. And they could even be donators. Thanks for your time.
