As these are specialised forums there is no restriction on how heavy, deep or technical you want to get. However, no detailed cave locations, please.
To help with indexing, please use a descriptive subject line, and keep each posting to one main subject.
After you have registered, please consider sending a brief post to the main forum introducing yourself, and summarising your interest and/or activity with cave databases, documentation, etc. - even if you are just "interested" at this stage, rather than active.
