Where to post

I'm new around here and I have some code which may be of interest to others, where should I post it?

Specifically, the question has been asked in the past if it is possible to program flash memory from a sketch. It's not for beginners but I have some sample code which does that.

Thanks.

Showing off is done in Exhibition. If you want your code/approach reviewed, Programming is a good place.

Exhibition it is then.

Thanks Paul.
