There, you will find people who are so knowledgeable in the subject of the group, that it will just blow your mind. Also, most of the groups have compiled extensive files that you can browse and download to add to your own library of recipes, techniques, skills and all around know-how. Many also have photos they've uploaded of all sorts of things like container garden ideas, canned food, food pantries and other efforts.
The best part of Yahoo Groups is the fact that they're free. Some of them require you to "apply" for membership through a moderator, but that's mostly there to keep out the riff-raff, and certainly none of my readers is riff-raff. :) Other groups you can join and have immediate access to the files and posts.
To join just go to yahoogroups.com and sign up. You can do a search for subjects you're interested in. Below are a few that I belong to that I highly recommend. You can search for them directly.
food-storage (must include the hyphen)
preserving-food (must include the hyphen)
If you have any other suggestions for good storage skills type groups, please let me know. The more the merrier.
Hope to see you around. Even if you're just a lurker on the groups. You'll surely pick up something to add to your treasure chest of knowledge.
