Sorry if this has been posted already, I couldn't find exactly what I wanted.
I created a sitebuilder, and I'm looking for some feedback (in general, not the code). Where could I post?
Any help appreciated.
There are no sites on the Stack Exchange for reviewing/testing applications, and I couldn't find such proposals on Area51.
But there are external websites for beta testing and reviewing:
If you would like feedback on a snippet of code, try Code Review. Otherwise, this type of question is rather localized (the answers won't be useful to the general audience), so not really appropriate for this network.
You can try asking in the relevant chat room, though.
Of course, you can ask about a specific design decision at UX.SE, as long as you can phrase it so that it's useful to others.
