The possibility of sharing gluten-free knowledge is the main feature in Glu.fi - without your 465 contributed content this site wouldn't be useful to anyone.
The content added to Glu.fi is freely available to all whom are interested in gluten-free and easy to find with Google. Other closed communities', and even Facebook's gluten-free knowledge may be difficult or impossible to find.
Since the shared tip is the best tip, I compiled all the content distribution possibilities on one page. When you want to share your content, you can use this page to always find the right place. If you haven't yet created an account, sign up now. If you do not want to register, you can send content directly to the administrator.
Remember to make sure that you have the right to share the content. So, if you are sharing your best friends's recipe for the benefit of all coeliacs, ask a permission.
If, for some reason, you can not or do not want to become a registered user, you can send the contents via feedback form or directly by e-mail to firstname.lastname@example.org. The administrator publishes content then anonymously.
This active celiac forum is here to help, if you need a peer, or you want a quick answer to your question.
Notice that anyone can add any kind of content into service. Also all advertised products are not gluten-free. Administrator is not responsible and you take full responsibility what you eat. If you notice vandalism or contents that include gluten, please notify the admistrator.
