A general guide for using the Forum with some rules and tips

The information provided within this Forum about localities is only given to allow reference to them. Any visit to any of the localities requires you to obtain full permission and relevant information prior to your visit. FMF is strictly against any illicit activities related to collecting minerals.

What is the purpose of this forum?
I created this Forum with the idea of creating a place to share questions and answers with other mineral enthusiasts and, most importantly, to try to provide a serious space where mineralogy questions can be discussed free of bothersome errors, free due the high standards of the administrators and moderators. We owe much of the success of this Forum to their fine texts; with them helping us, our Forum looks "clean" at least in terms of its scientific content. During my mineralogical journeys I frequently receive mail asking many different questions. When I answered just the person who sent the message, I always had the feeling of something being lost. By publishing all these questions and answers on the Forum, others can share our thoughts about minerals and mineralogy. That's why I created this Forum. Jordi Fabre

FMF English Forum moderated by John S. White and Peter Megaw

I have been serving as a moderator for the English version of FMF Forum now since 2007. This does not seem possible, but one cannot deny the facts. It has been a lot of fun for me and I hope that visitors to the Forum are enjoying it as well.

We are now (Dec. 2009) adding a new face as an additional moderator - Peter Megaw. Actually Peter is not new to regular visitors to the Forum as he has been one of the most prolific contributors to many of the threads. He brings awesome credentials to this role, all of which I do not have space to detail here. He is a Consulting Geologist and co-founder of IMDEX/Cascabel and MAG Silver. He got his B.A. and M.A. in geology at the University of Texas and a Ph.D. in economic geology from the University of Arizona. He has explored Mexico for 30 years and has made important ore discoveries at Juanicipio-Fresnillo, Zacatecas; Platosa, Durango; and Cinco de Mayo, Chihuahua.

Peter has been a dedicated mineral collector since 1977. Living in Tucson, Arizona, he has served as exhibits chairman for the Tucson Gem and Mineral Show™ every year since 1984. His minerals have won many trophies for him in various competitive displays. He was recently named a consulting editor for Rocks & Minerals Magazine. There is much more that can be written about Peter but space here is somewhat limited.

The FMF Forum has an anti-spam system that means that you cannot add links to messages. To give you an idea, each day we get about 20 attempts to post ‘rubbish publicity’ on themes that have nothing to do with minerals. So this system keeps the forum... (View full message)		Joan Fabre
Tucson, questionable prices?	Author
Jordi Sadly I could not make Tucson this year.

Very little mineralogy in mineral collecting today	Author
One thing that troubles me greatly about the mineral hobby today is that very few collectors appear to have much, if any, intellectual curiosity about minerals. The focus for most collectors appears to be only beauty and perfection, rather than rari... (View full message)		John S. White
