I'd like to add this fantastic forum and community for all the help with typesetting and formatting my thesis. Is there a defined way to do it/refer to TeX ?
I was considering doing this too (printing now) -- but I decided not to do it. Typesetting help is wonderful, but in the usual case it's not quite a research-level contribution. Maybe you'd consider adding the relevant credits to an "About the Document" section at the end instead?
