Tclkit, Metakit, and Catfish are F/OSS (Free / Open Source Software). See the respective section for pointers to mailing lists, wiki's, and other documentation.
I am always interested in solving problems with each of these software packages, but I cannot guarantee response in terms of helping people understand various features or language issues.
There is a feedback forum to enter new problems and to search for issues which may already have been resolved.
For commercial projects, feel free to contact me at any time, and let me show you that when I say that "my goal is to help you succeed" this is not an empty phrase. Problems and bugs do happen, and in my experience it is better to solve them now than to have them bite you later, often in nastier and more urgent ways.
