Where to put Guides and How to ?

Hey.
Since I use some specific features or formulas very rarely, I often create a guide for myself that I can use next time.
They are typically described in great detail so that I do not have to spend a lot of time next time.
Now I just ask if there is interest in me uploading these to www.excelforum.com and if it is possible at all.

Best regards
